A very neat coffee experience, its amazing how coffee tastes when its made thoughtfully. I appreciate the detailed descriptions of each roast and the helpful suggestions from the barista. Lots of space to sit and sip.

A sophisticated cup of coffee for sure. You have several bean options when you walk in, all well described (think wine flavors). You can order any type of coffee (cappuccino, latte, flat white, etc.) with any of the coffee flavors. I chose a cold drink that was coffee and lemonade, that was amazing. I was surprised that I was actually drinking something that tasted so good that I had never tried before. This place is also quintessential Burlington from a vibe perspective.

First I will say that the cappuccino I ordered was really good. It was everything I would expect out of a great cappuccino. This comes after scratching my head and looking at all the information about different coffee types. The inside scoop is when you stand there reading the alien language wall menu for over 5 minutes you earn a free 10 minute class on how to read the menu and select a drink from a bilingual barista. The class was helpful and I somehow felt accomplished. So off to ordering as I could see the next person in line was approaching 10 minutes of menu staring contest. Service was good but the end result was no different. I thought after all of that, Im drinking a cappuccino. I fully expected to see into the future, or grow antennas or something.

Maple oat iced latte was delicious and refreshing. Nice ambiance.Yes kind of pricey but you don’t feel ripped off because it’s good 🙂 wish I had a chance to try more

Non-pretentious, friendly place with fantastic coffee, the love for the craft and expertise is apparent.

Super cute place. Really friendly baristas and great coffee. Really brightened my morning!

It was a cold and rainy day ... when we meandered into Onyx Tonics. I ordered a Kagumo black coffee. The barista redirected me away from adding cream. He said doing so would dilute the subtle flavors of the coffee.The coffee was delightful. The Cafe has a clean European look to it. I highly recommend making time to stop in here, especially on a cold and rainy day.

Best coffee in Burlington. These people know their stuff!!! They have rotating beans with helpful tasting notes. On weekends if you’re lucky (read: early enough) you can snag a pastry from a local baker or two.

I had the most well balanced and toasty iced maple latte. I was blown away! I don’t normally like lattes, and got it on a whim. So happy I came here!

One hella of a good coffee place. You’re in for a treat with a creative barista who’s in it for the love of coffee. Didn’t expect less from a Vermont coffee shop.

Some very tasty coffee, artfully made with great raw materials can be had here. There are many curated blends to choose from and excellent friendly team serving them.The honey blossom were donuts were tasty and generously filled and very tasty.Almost like they are the made with sour dough.Definitely a must try!

A fabulous gem of a coffee spot in Burlington, VT! I honestly dont know whats better - the coffee, the people who make it, or the vibe you get as soon as you walk in. LOVE everything about it!!!

Very hard to contact. Called several times but no one answered the phone. Online order didn’t work.

The barista was attractive but very pretentious. The iced and hot coffee were very good and would definitely would recommend.

Definitely a brewed awakening! I like the choose your own adventure menu with different coffees and ways to prepare. The description of my choice was spot on and different from any other coffee Ive had even with oat milk - yum! The family enjoyed the hot chocolate and baked goods as well. Worth a visit!

They weigh the beans for espresso shots, the beans are fresh, the people are friendly. You cant ask for much more!

Super friendly service, very knowledgeable and a great coffee selection. It is a must for a coffee aficionado.

Best coffee in Burlington! The coffee is amazing, and you can even choose the espresso they make it with. They make good specialty drinks too (maple iced coffees really good).

Im really glad I decided to listen to my fellow reviewers for this coffee recommendation, holy cow this is a truly awesome place. These folks genuinely care about making great coffee and arent pretentious about it either. Seats at the counter so you can have a friendly chat with the barista and they make a great cold brew.

Cold brew was really good. Surprised I was able to pick up on the tasting note.

Probably the best cold brew I have ever had. Delicious coffee and such a cute place.

Good coffee and excellent service!

Best coffee in Burlington. Delicious light roasts and expertly prepared.

Fantastic coffee spot in Burlington! The baristas are passionate about coffee, and give an accurate description of the different coffees being offered that day. Plenty of seating with a cool hip feel.

Excellent artisanal coffee. You can pick your beans source even for a latte. They measure the weight of the beans you selected to make your coffee. Impeccable! I picked the Ethiopian beans which were beyond delicious.

Thanks for being open during all of this, despite a change in how the shop interacts with customers(no dine in services at this time.) The whole team still shares amazing singe origin coffees from a wide selection of local and national roasters. With a menu thats constantly rotating, allowing long time customers to continue to find something new and interesting in their morning cup. thank you all and much love.

Very good coffee (and hot chocolate!) and knowledgeable baristas

Best espresso I’ve had all year. I drink a lot of coffee, worked as a barista at a high end roastery, and am pretty snobby about my coffee in general. This is really, really, really good coffee. Even my wife’s decaf espresso was pulled perfectly, which almost never happens.And even with the high quality, the staff is super down to earth and kind. Way to go, Burlington!

Best specialty coffee Ive found in Burlington 👌🏼

The coffee was made quickly and it was delicious. Definitely stop in if youre in the area.

This is a coffee stop for purists; intelligently selected beans from local roasters carefully crafted in traditional cups. Hand-poured or espresso. No crazy gemic flavors. Just good simple coffee. And some doughnuts.

Maple Latte was out of this world. Also this has got to be the coolest name for a coffee shop Ive seen.

Perhaps my 5 star review is redundant but this place was the best coffee place in Burlington. The maple latte is a must try! Staff was so helpful and courteous. Whenever we drive through Vermont again, this coffee place will be on our must go-tos. Keep up the great work Onyx Tonics!

Amazing folks who offer such a beautifully curated, dial in menu. This is *the* place to try different coffees and theres always something fun and different on the menu!

Great vibe. Not a ton of seating so if youre going and planning to hang out, you might have to share or wait for a table to open. Service was excellent and our drinks were delicious.

My favorite place to work. Amazing coffee, great atmosphere, and very friendly staff.

Cute and small. Sadly a small selection as well. I could see them growing into something larger, surprised based on the demographics of the area that they have not already, covid excused.

Delicious espresso .. the atmosphere is great to go with a friend, bring a book .. just hang and chat. The baristas are always warm, friendly, inviting & knowledgeable!

Best coffee and good people!

I heard a lot about this place from the locals, so I decided to check it out. It’s overhyped and overpriced. I wasn’t too impressed by the coffee. The service was excellent, though.

Tried this place for the first time today and had the Maple Latte. It was super smooth and not too sweet, perfect latte!

Favorite coffee spot in Burlington! Have yet to be disappointed here! Knowledgeable and kind employees cool atmosphere!

The menu was a little confusing...

Best coffee in town and its not even close.

Super quality, fairly quick and always courteous

Amazing coffee in Burlington. Great attention to detail and super high quality!

Very friendly and great whole bean retail selection.

Overpriced, but good coffee, the tipping options are a bit ludicrous. How do you ask for a tip equal to half the price of the coffee?

I go out of my way to come here. They really put so much thought and care into every cup, all for the same prices every other coffee shop is charging, including the big corporate chains that get wholesale prices for pretty mediocre tasting coffee. This shop is all quality over quantity, people over profit, coffee over cash 😂, and in this day and age that should be lauded! Onyx Tonics forever!

Got a maple latte. Couldn’t taste even the slightest hint of maple, and is overpriced for how small of a cup it is. Much better options in the area.

The staff was real friendly but the coffee tasted sour at first. It eventually grew on me but I was still disappointed. I will try a different drink next time if I come back.

Good espresso

Some of the best coffee in town, hands down. Nice seating, friendly staff, and a wide selection of coffee and coffee adjacent bevs. Well worth venturing the block and a half from church st.

Delicious coffee!!!

Excellent coffee and the raspberry glazed donut was one of the best donuts Ive ever had.My only criticisms were that the prices are a bit steep and they only serve 12oz cups

Excellent experience. Thank you

Best espresso in town! This has become my go to café in Burlington. Staff are super friendly and great to chat with. Interior aesthetic is cohesive and put together down to the little details. The bar, is perfect for doing standing work, which I really appreciate. However, I wish that the seats were comfier and that there was more natural light in the back.

Truly flavorful cold brews and iced lattes. Feels like an artistic expression of coffee. Sourdough donuts were also a welcome treat as well.

A spacious and comfortable coffee shop for people who like coffee to be complex and flavorful. The ordering process is complex, but the staff is there because they love coffee in the way people love fine wine. The flavor profile of each roast will be on a chalkboard to your left, and you can select how you want your roast prepared. This is not a spot to get a take away of a cup of autodrip to keep you up for work. This is a wine bar for coffee. Bring a book or your laptop and enjoy the flavors and the setting.

Very nice people. Not snobby. Great coffee sourced from excellent roasters!

Top drawer espresso. La Marzocco machine makes their varied espresso selections come alive

If youre a hipster and you have a few hours in downtown Burlington, this place is a must visit. The coffee is delicious (according to my friend, I dont actually drink coffee) and they have a lot of tasty treats. The only reason its not a 5/5 is because its pretty pricey.

Good coffee good people!

A gem. More than just another high-end cafe, which are too often cold and cookie-cutter, Onyx excels at the best aspects you want in a friendly neighborhood locale: exceptional drinks, authentic staff, and a beautiful granite bar where regulars can congregate and gab away leisurely amongst themselves and with the staff. Additionally, the excellent wifi makes it a great place to plop down and do some work. Highly recommended.

I asked the barista for a flavourful cup of coffee and he patiently explained what he had to offer. We both got two different products and both were great and memorable. Amazing dedication to the craftI recommend

Absolutely the best coffee around! Ive never had coffee as good as they made me today. Nice location tucked next to VT pub and brewery. Do yourself a favor and try Onyx Tonics now!

To call this place a coffee shop is to sell it tremendously short of what it actually is: an Elixir of Life Dispensary. I frequented this establishment multiple times a day whilst living in Burlington. The outrageously attractive and charismatic staff are not only excellent conversationalists and joke tellers, but also experts at their craft. Sourcing only the finest coffees from the ends of the earth, it seems these baristas/artists will stop at nothing to ensure that every drop of perfection that is associated with their name is equivalent to nectar of the gods.Ever since moving away from Burlington Ive felt that a large part of my soul has been ripped out and left at 126 College Street. I am planning a pilgrimage later this year to retrieve it.

The best coffee in Vermont, hands down. This shop is all about the quality of the drink but the setting and interior is very unique as well. Try the siphon coffee and enjoy the process of making it as well.The espresso is Devine and the equipment they use in the shop to make the drinks is the finest in the world. Highly recommended. We are going to miss it on our trip back to New York.

Little pricey but delicious

Had the Maple Latte as well as a regular latte. Both were great. Staff was friendly. Vibe was easygoing.

Excellent coffee, and donuts were delicious also. Very friendly staff. Wait can be a bit long for a hand pour, but likely only during busy times.

This is my GO-TO place for a coffee meeting. I have had great meetings here due to the relaxed atmosphere, the WiFi, the fact that there is a place to plug in AND THE COFFEE. Jason is an artist and his coffee recommendations never disappoint. This isnt a coffee shop; it a coffee experience. If you need to meet someone in downtown Burlington over a cup of coffee, this is the place to do it.

Nice atmosphere, excellent beverages, a little on the pricey $ide

One of the best Latte I’ve tasted outside of Italy. The barrista was really nice and took the time to go over their café menu with us.Great place to discover!

Delicious coffee and treats with no plastic or paper waste!

Amazing coffee, friendly staff, indoor atmosphere could use a bit of improvement but its ok.

Very well put together coffee selections every time I go.

If you like third wave coffee, this is the place to go. They know their stuff.

The barista recommended her favorite hand poured coffee in stock, an Ethiopian with notes of blueberry, citrus, and black tea. It was delicious! Trifecta of a great shop: quality coffee, knowledgeable staff, and excellent service.

By far the best coffee in town. The baristas are top notch and extremely skilled. I would recommend this place to anyone who loves a great cup of coffee.

Awesome coffee and an awesome venue. Unique artwork on the walls, modern and slick. The owner/ barista is super informative when explaining the types of espresso available and can make a mean cappuccino. Definitely going to be a regular spot for me to get caffeinated and do some work.

Best Coffee in Burlington!

Perhaps the best cold brew I’ve ever had.

Really great coffee. A very nice execution from well sourced beans. Lots of laptops. Barista was very nice and knowledgeable.

Blew me away. I have run coffee businesses and let me tell you this one is top notch. Baristas are excellent my espresso was pulled perfectly. My capp was served 6 oz perfect espresso milk foam balance free poured (as it should be) with a beautiful tripple heart on top. A little pretentious but when your producing coffee of this quality you have the right to be.

Probably my favorite cafe in Vermont!

Phenomenal coffee. And the baristas know exactly what they are doing.

My favorite spot for coffee in Vermont. The husband and wife ownership team are fastidious and produce quality products with love.

It was described to me as a coffee shop for baristas and coffee aficionados. Its definitely not a starbucks, so dont expect super syrup frappe drinks. The staff was pretty cool walking me through the beans they had and what the flavor profile of each was like depending on how you took it (espresso, cappuccino, or filter).

Well made cappachino staff very knowledgeable about brewing methods,. Limited sweetener options

Cool place if you know your coffee! And can get a seat!

Best coffee shop in town. Great service, great coffee (and tea!), cute place. Highly recommended.

Well made coffee. They use pacific brands barista soy which is a good soy, not too sweet.

Nice variety of teas but water was just warm.

Every drink Ive tried had been delicious. The baristas are friendly, and the space is small but cozy.

Nice atmosphere, friendly staff, great coffee with exceedingly fine attention to detail. Highly recommended.

Wonderful coffee served in a great venue. Simply the best!

Great coffee, awesome vegan options and vegan donuts. Relaxing decor, dog-friendly venue.

First time in this cafe..lovely mocha..highly recommend.

These folks really care about the quality of every cup they brew. There is always three different beans available to try with unique and delicious flavors.
