Been here several times. Today I tried breakfast sandwich and Jasmine tea. The sandwich is delicious and tea is very refreshing. Overall it is a great place.

Loved this place! Amazing food and artsy latte arts, decor is nerdy (think sci-fi) and tables are not too cramped together. Prices are reasonable. A nice and quiet place to read a book, work, catch up with friends, etc.

Bitter + Sweet used to be a place I recommended anyone visiting the South Bay. I used to go daily to grab a cup of Secret Breakfast and chat with the Asian lady owner (long time ago). Im a bit sad that the workers now are unfriendly / borderline rude.I went to get a cup of the usual velvet latte and a breakfast and sat at the counter. I was told by the worker that I cant sit there. Literally just you cant sit there without looking at me. Ok... awkward silence followed by the sound of the chair.Im the only one waiting for my drink and she calls out velvet latte! I wasnt sure if it was even mine because it sounded like she was calling out to someone else.The cup looked like it wasnt washed. There were dried up spots on the cups rim.When I was done, I went to go put away my cup/dish. The worker was using the counter I was told I couldnt sit at to be on her phone. No thanks or have a good day or anything.What happened to this place?Also the ambiance is a bit off with the arcade machines. The machines are either turned off or just has no sound. Its like they arent sure whether they want the arcades or are annoyed by people using them. Space would be better utilized without them.Call before you arrive because they seem to also be pretty liberal with their hours. When I arrived, there was a sign on the window that said they are closing early that day.Im still giving them 2 stars because their drinks are good.I recommend going to Voyager Craft Coffee for a happier environment with better staff / drinks to boost your day.

Great coffee, but the man behind the counter is a bit rude. I guess that’s the “bitter” part as in the name?

Good coffee. Teriible customer service. Im not expecting to be fawned over but dont tell me Im wrong about something when your signage says otherwise.

I used to adore this place pre-COVID, but since 2020, it’s unfortunately been declining. The hours of operation are sporadic at best, the staff is pretty rude now, and the quality of coffee doesn’t justify the trip anymore.For example, certain food items won’t be available at the whim of whomever is at the register. If the staff doesn’t feel like warming food or making certain items, they will just refuse to make it even though they have the time and energy to do so.I want to continue supporting this cafe, but they’re not making it easy. I hope things improve as time passes.

Very friendly and helpful employee made me a special blended drink to my specifications which wasnt on the menu. Love it! Lost a star because croissants are overcooked, slightly burnt and dry. Creepy mask in the rafters. It doesnt make sense with the rest of the decor which is very pleasant to hangout in.

Good coffee shop with bakery. There are not a lot of seating inside so you might have to buy to-go. One of the coffee shops that I actually like their latte with non dairy milk. Cake was not as sweet, which is what I like.

This is nice little coffee shop. I always like coming here for my coffee fix when I am in the area. Its usually not crowded in the mornings.Some of their drinks I have tried:Red Velvet Latte: While interesting, I didnt like it very much. Milk taste totally overpowered everything else in the drink.Black Sesame Latte: was very nutty, had slight sweetness to it along with mild espresso flavors. Its more calm-me-down than pick-me-up but I definitely liked it.Lavender Latte: very floral tasting drinkKarl The Fog: is pretty interesting, and my favorite drink to get here. Its milky, has good tea flavors peeking thru and rightly sweet. Its no Chai, but if thats your thing, or if you like tea, you will certainly like it.

Bad customer service asian barista was rude.

Few places capture service, hospitality and creativity. Daniel and his staff prepare an artistic coffee experience with love and dedication. Giving back to the community by way of donations and connecting with their customers with personal service is only outdone by the great taste and choices of coffee confections! Truly a great place for a coffee and dessert. I highly recommend this experience!

Unique red velvet lattes are delicious. Great atmosphere and the staff is very friendly. I usually get the soy velvet latte, you got to try it!

Place that feels cozy and modern. More than enough two-tabled seats. A handful of places outside. Great wifi service but make sure to purchase something to get their code

I got their espresso tonic only. The syrup for the tonic was a little on the sweet side which threw off the drink. They use a sodastream, which is awesome since I have one at home, but it wasnt as crisp or carbonated as I would like it to be. The vibes in the cafe was pretty cool probably packed during non pandemic times. A little out of the way for me, so not sure if I would be back.

Changed the working hour but didn’t post it online. Wasted my time driving there.

Grouchy! But I like places with a bit of character. Good coffee, made with care, Midwife and Baker pastries.

Good special coffee. Nice service. Inside is a bit small. Can be crowded on a raining day.

Great coffee, really awesome latte art, delicious food, chill ambiance, and nice staff. There are board games, Street Fighter, and Pac Man to play with friends. It’s a good place to study and chill. There’s plenty of seating. I highly recommend the black sesame latte (with slightly less sugar) and the prosciutto & brie panini.

Came here on Sunday, and really enjoyed here. It is located in Cupertino, and it is a cute place. Great coffee and good desserts. Staff are really friendly and helpful. You can ask for WiFi passacode per model device.

Local cafe run by the owner. Consistently good coffee.

You should go elsewhere. There are coffee shops dime a dozen and pretty decent as well.

Tastes yam sweet in the end of every sip with latte art..

Highly underrated. Very smooth latte and cappuccino - great coffee. Go here.

Fun coffee shop with marvel-themed art, games. Great flavored coffee, with unique specialty lattes (red velvet, rose). Can get a bit crowded, so seating may not be guaranteed & has 4-hr limit for WiFi to keep the crowd moving.

Finally came here to try their red velvet latte. Its a standard latte flavored with red velvet powder? Its not too sweet and still retains the flavor of the espresso. Nice vibe here. They also serve beer and wine. They use Sightglass coffee for those coffee snobs out there.

Liked the red velvet coffee.

Enjoyed the mocha and the hazelnut napolean cake. Place has 3 older arcade games that you can play for free for nostalgia. Pacman, Street fighter II and mortal Kombat. Its a smaller cafe so if youre with a large group it can be hard to find a place to sit together depending on how crowded it is at the time.

Amazing cappuccino and pastries. A little on the pricier side but one of the very few best coffee places in Bay area...

Youre better off going somewhere else

Staffs were helpful and I liked the ambiance of this place.

Closed at 1 pm on Saturday where as the timing on door and website says open till 2 pm.Understandable in COVID timer and lesser customers at some hours, but please make an effort to mention the time at door / website

Same issue as Denis. Went there Wednesday at 7:30am and it was closed, even though the door sign says they open at 7.Nothing on their Instagram signaling they wouldn’t be open today.The inconsistency is frustrating.

Lovely coffee from an espresso machine.

Lovely place to meet. :)

The place is nice, good coffee and nice staff but internet is terrible. Came to work but had to leave:( good for coffee meetings with friends, but will not recommend the desserts though

Too sweet and way too pricey for a self served place.

This is a really nice Cafe, the desserts are absolutely amazing! I had the cheese cake and while it was small it was delicious and flavorful. The staff also is very nice and attentive, they gave directions to water and other amenities without being asked. As far as decor, it was very homey with art all over the place and had a very chill vibe.

I love their red velvet latte. It’s a little bit sweet for me, but still the best.

I need to come again to try the coffee. Their matcha latte is quite unique, and their cakes are great. Good vibes, nice environment.Edit: tried their coffee. Maybe a bad batch, but it tasted mildly burnt. 12 oz of below average latte for 4.75 is a bit disappointing. if it was 16 oz for that price, then it might have been worth it anyways.Unless you like their signature drinks, its below avg.

Great place to have coffee. Seating is limited though

I’m a bit torn about this place.Pros: one of the few coffee shops with a comfy couch, games, puzzles, and overall smart and cool layout and decorationCons: I cannot get used to its coffee. Even their mildest blend is just really strong and unique in flavor. I appreciate coffee being an adventure, but sometimes I just want a mild, relaxed cup of coffee. I was not able to find that here.

On their door it says open until 4pm on Sunday, drove all the way but closed, don’t post wrong hours!

Came in for a chai one morning, stood at the counter, and was stared at for a good 30 seconds by the guy foaming some milk before he deigned me with a greeting. I get that he was working, no problem, but I think it is a bit crazy to look at someone for that long and not at least say Hello/Just a minute, especially after I say Hi. I order my chai (only one size, OK) to go and was then surprised when he handed it to me and this $5 cup of chai that I ordered still has a good 2 inches to be at the top of the cup. Maybe Im spoiled by my usual haunts, but I am way more used to getting a full cup to nearly the brim. I didnt order a coffee and ask for the barista to leave room. Perhaps a sizing issue with their to go cups? (again, only one size offered, so that just seems odd)Chai itself ended up being OK (love that they use David Rio, my go-to), mainly because the ratio seemed a bit off - it was overpoweringly soy milk and not chai.Seemed like a cute place, but I wasnt impressed.

This is a great place to sit, indoors and out. Outside is a quiet neighborhood with the Cupertino Library and Civic center nearby so its a very family friendly place. Inside, they make the most of the space and the tables are comfortable to work on. There are three arcade games that have their volumes disabled so its actually not distracting at all. The service is fast with a smile. Wife says the cafe latte was excellent. Tiramisu cake we ate was not moist enough, but was not too sugary which is good.

Absolutely love this place! The coffee is great, the ambiance is great, and the service is great too. I love their red velvet latte, and the secret breakfast ice cream(yes, they have ice creams as well!!)I really like the artwork on the wall, and they even have arcade machines!! Free WiFi, so all in all, an amazing place to hangout at!

I usually came here to have a coffee but today I decided to try their vanilla bean ice cream. It was really good and I like it. Better try their other desert.

Great tea and coffee with a nice variety. Strong, flavorful, artistically crafted. The barista/owner is friendly but no-nonsense, and the space is bright and clean. Really like the retro arcade machines (on infinite free play!) that take me right back to my childhood. Didnt think Id find a nice cafe right around the corner thats equal to, if not superior, to the trendy cafes in SF. Will definitely be back!

The espresso drinks are pretty fantastic. The ice cream isnt bad either. When I visited, they were out of tiramisu, which was a bummer. Ill be back to try that offering for sure.

The barista was very rude. Rudeness is the last thing you expect from a coffee shop. On top of that they didnt have half the items from their menu. I dont think I will ever come back.

Delicious espresso.

Great prices, coffee was really good as well! Service is as good as it can be for a 1-man coffee shop. Seating areas are nice, I was able to get into flow within a minute or two while writing. Bathroom is clean, and they have a Pacman arcade machine in the middle of the cafe!

I always come here for their red velvet lattes! Very cute designs and they are tasty too. Its a nice place to grab coffee with a friend and chat but it can get crowded with people studying. They have a good selection of desserts and snacks if you are looking for something sweet or a quick bite to eat.

I absolutely love love love their Red Velvet Latte. It is heavenly. I have yet to see it anywhere else, and am so glad because Bitter+Sweet does it so well.They stay true to their name, because their drinks really are at the intersection of bitterness and sweetness - which is what makes this place so good.The ambience is great - its peaceful and quiet enough to have a quick date or study session. Even though the location is pretty small, I have never seen this place get crowded.This place is definitely one of my favorite coffee spots. I always make an excuse to stop by and its always worth it.

One of the top in terms of atmosphere and service. Their Red Velvet Latte is the kind of flavor that cant be found anywhere else. The ice cream is also top notch.

I love all things black sesame and went just for the black sesame latte. It was quite tasty.

The local ice cream was great! Ill be sure to come back to try the velvet latte next time.Make sure to ask for the wifi password. Youre unique code is given to you on a piece of paper with a 2 hour time limit. I guess they must have a lot of customers buy a coffee and stay all day. I dont blame them. Its a very nice environment.

The coffee here is always delicious. Their desserts are tasty and their vanilla bean ice cream is out of this world.

Espresso is not good. Too acidic. Ambience and atmosphere is very nice. If you like sweet drinks then their specialty drinks are ok.

Chai tea latte was excellent. Feels strange being inside w/ all the furniture stacked against the wall.....but thats the state of things with COVID still lurking.

The staff is friendly and helpful. The red velvet very pretty and very popular. Some tasty high end loose leaf tea offered. Unfortunately the seating is uncomfortable for any sort of duration. Couch seating is limited and benches and chairs lack cushion. A neat place to try but not the best for studying.

Unfortunately the staff we interacted with was rude and the coffee is over priced. The largest coffee you can purchase is 12 oz and they literally MEASURE it out. If you bring your own mug they will measure 12 oz out. Any easy place to skip. The coffee was good though!

Hands down the best espresso drinks around. Cozy spot, serving excellent pastries from The Midwife And The Baker, as well as sandwiches, cakes, ice cream, beer and wine. Unmatched latte art.

Great place with a good vibe and helpful staff. The coffee is particularly smooth and tasty.

Red velvet latte was so good - very smooth, not too sweet. Nice relaxing ambiance. Friendly staff.

First time visitor, on the road to LA. Barista girl was sweet, is a real cutie, and made me a great iced red velvet latte w/almond milk for the road. Even kindly offered a double shot to keep me awake. Would love to come back, and hopefully shes there again! Definitely bittersweet I cant be here more often.

A good coffee shop is Cupertino? Surprising but its true! Nice selection of desserts, sandwiches, and pastries from the Midwife and the Baker. The coffee cocktails, such as the espresso tonic, are also worth trying.

Very small space with limited seating, so I wouldnt prefer to go here for studying. The coffee is good though and the arcade machines are a nice touch.

Very good coffee -- Some of the finest you will find. They use Sightglass coffee, which I find hard to beat. Skillful and professional staff. Nothing at all bad to say, except that the prices are too steep. $4.25 for a 6oz cappuccino, $4.50 for a plain croissant. But, very good cappuccino in, even though occasionally it will be delivered at a slightly too low temperature. As of his week, the Classical music has disappeared. I hope it comes back, since it is rare to find it at other cafes.

Bitter+Sweet has style. Ive been going there for several years and they have consistently good staff and consistently good coffee. I highly recommend their cold brew.

Rude service and terrible manager. He was very impolite despite the fact that I purchased a drink from his cafe. I came with a friend but the time was ruined because of his attitude towards me. He even came up to me after I was sitting to pester me to move my computer from the desk. Even though I had purchased a drink, I had not even finished the drink at this moment, I felt rushed to leave. Overall, this cafe is a waste of time and money as paying customers are shooed out of the door after their seats are barely warm.

Cool environment, but the lattes were very underwhelming. Felt like I overpaid and made better ones at home. There are much better places for coffee in the Bay Area.

I am sorry but somehow this place did not impress me. The decor-yes but the coffee-big no for me. Went there over the weekend, place was pretty busy. The place is wonderfully beautiful from the inside, it isn’t very spacious from inside but they also have sitting outside. Ordered a cappuccino, wonderfully presented BUT tasted so bitter. From my experience, the worst coffees are the ones that are served without cleaning the filters first! After couple of uses the filter makes the coffee taste super bitter which is exactly what happened with my coffee here. I went there with so much expectation after reading all the good reviews but alas I’m sad with my experience.

Great place, known for the red velvet coffee which is really good! Tried it with the almond mile and it was still just as good if not better! Hard to find but worth going to! Highly recommend if youre in the area and need a caffeine boost

Im not sure if it kept me with a sweet or bitter aftertaste... :-)

Free wifi: You need to ask the staff to get a code and it will only last for 2 hours.Coffee: Ordered a cold brew and a latte. The cold brew is all right and we like the latte. They use beans from sigh glass.Atmosphere: chill and relax.Parking: there is an indoor parking behind the store.

Not a bad cafe. Pretty aesthetic environment to do work in. A little bit expensive but everything in this area is expensive honestly. The chai latte is not very strong but its tasty. Their candied orange bread was also not bad.

Tried their yuzu matcha and red velvet. Their yuzu matcha was really great. The cafe is a nice cozy place to study and meet people. It has arcade games!

The cafe was pleasantly quiet on a Saturday afternoon, workout being deserted. Decaf cappuccino was very nice. The fig and prosciutto panini was to greasy. Staff were friendly. The single unisex restroom was nice and clean.

Service sometimes is not the best. It looks like people there dont want to make money. We arrived 3 min before 11pm. The guy on ciders have been really nice and sold us the ciders. But when I asked to have a piece of cake, the girl on the other counter didnt even look me in the face and just answer me it was already too late. Too lazy to cut the cake and make extra money for Humboldt Pie.

The place is not bad. Got a red velvet coffee, and it had too much sugar and too sweet

Their desserts are great. I especially like their Tiramisu.

Pastry DEICIUOS!! Regular house coffee tastes old and astringent, better luck on crafted coffee drinks? Not sure yet, go back and taste next time!

Great coffee. Humphrey Slocombe ice cream. Laid back vibe. Memes on the chalkboard. What more could you want?

Pricey..Bad customer service. The staff was acting high n mighty.. In fact one of the staff was very rude. This was my 3rd visit. I felt it during my earlier visits but I gave them the benefit of doubt.We went here to get some coffee and a sandwich. They ran out of house coffee ..and that was in the morning.The order was messed up to begin with. The latte was warm. They wouldnt reheat ..same with the macchiato. . They remade the machiato but the way they responded was very rude. I felt they are very condscending towards non coffee afficianadoes..Suggest they first improve their customer sevice and attitudes ...

I got the red velvet coffee and it tastes incredible. However, they put ice all the way to the top of the cup then poured the drink in. You should definitely drink it hot if you want more for what you pay

The coffee is great, the ambiance is great, and the service is great too.

Got a danish and a red velvet latte. Both were delicious. Ill definitely be going back!

Red Velvet coffee for the win! I would come back daily for that. If only this place was closer to me..

Delicious red velvet

Bad cheap coffeeThey refuse to give you half and half saying there is no enough to steam Most rude employees.. U go have a morning cofee to relax and start your day. You dont need to start it with people dont smile and dont know how to serve you .

Amazing coffee! Pretty good desserts and sandwiches as well. And their ice creams are fantastic.

Red Velvet Latte is highly recommend! Good place for hangouts.

I lived their Rose Latte. Will be coming back

I love coffee and this place uses some of my favorite beans(Sightglass). You should also try their ice cream(theres a cereal flavored one made with rum I believe).

Excellent cappuccinos! Great breakfast sandwich! Great place to work for a couple hours, too.

Nice atmosphere. Good coffee. Raisen crasount was delicious.

Wi-Fi inconveniant. One is a given a one time password that only works for one user. Really ? Come on. Dearth of power points. These are clustered in a corner. Majority of seating positions will have no access. Coffee however is good.

My home away from home when I used to attend the local CC. It can get pretty packed in during peak hours (lunchtime or just after dinner), but if you come in when its not too busy it has a nice ambiance. This is my absolute favorite place to grab a latte (red velvet please!) and do light work on my laptop. You can get a WiFi code at the register that lasts for 2 hours with your purchase. The baristas and the owner are friendly and knowledgeable, ask if youre not sure what to order! (P. S. The bathroom has a sliding door)

Great cappuccino, nice setting. They use Sightglass coffee and it tastes and looks wonderful!

Delicious offerings and in a convenient location! Id highly recommend their red velvet lattes, which are a treat for the palatte and the eyes!
