Onyx Tonics Specialty Coffee

Had an exceptional, and unique cup of coffee. Great service. It's also reasonably priced considering things in this area are getting unaffordable. HIghly recommended.

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).

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!

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.

Such a kind and wonderful staff who make the best coffee and coffee drinks in Burlington. Wonderful rotation of specialty beans and the descriptions are accurate and helpful as well (even have a “flavour notes” section for how adding milk to each coffee changes it!). A place I go back to every time I’m in town. One of my Burlington “musts”.

The folx are tonix are extremely friendly and knowledgable. This is genuinely one of very few places in burlington or vt that will serve a perfectly pulled shot of espresso perfectly every time. They use perfect beans and their menu will give you helpful insight into what you’re ordering. Iced americano is perfection. Drink coffee here.

The absolute best coffee in Burlington. Really creative and delicious specialty drinks — had the C+C espresso and tonic and it was UNBELIEVABLY amazing. If you’re overwhelmed or have questions, the staff is really lovely and outgoing.
If you’re looking for somewhere quiet to work, they have lots of seating and the vibe is very chill. Love, love, love this place 💜💜💜💜💜💜

Delightful coffee experience. Unique coffees, knowledgeable and friendly baristas. We recommend.

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.

Very good coffee, very good cookie

Some of the staff were a bit unwelcoming and openly mocking customers so I changed my review.
