Onyx Tonics Specialty Coffee

If you like seeking out high quality, thoughtful coffee shops. This is it! 10/10! High quality espresso and specialty drinks. My only regret is not buying more coffee.

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.

My latte stop whenever I am on Downtown Burlington, thank you!!

Went to Burlington for a short trip, dropped by to quickly get a takeaway coffee, and was pleasantly surprised by the quality of the coffee. As an avid coffee drinker, I can assure you to visit this place if you’re in the city. The barista definitely understands how to handle your coffee, he didn’t burn the milk in the coffee and all the notes profile of the beans came through.

Great coffee and I’m sure they take their craft seriously. But the barista really makes you feel like you shouldn’t even be there, like he is bothered by your very presence. I don’t know if pretentious is the vibe they’re going for but they nailed it.

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, I'm drinking a cappuccino. I fully expected to see into the future, or grow antennas or something.

Great vibe. Not a ton of seating so if you're 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.

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!

Single origin espresso is very good. Served with sparkling water to cleanse your palate before sipping. True to how espresso should be enjoyed.

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.
