Great space with just enough noise to make you feel relaxed. The menu was a bit confusing g so went with my old standby - extra hot mocha. The service was fantastic as was the coffee. A bit on the bitter side but it was balanced out by how rich it felt. It was perfect on a rainy cold afternoon. This was the third coffee shop I tried in town this week while I visited from Berkeley, CA and I'd definitely recommend it. read more

Onyx Tonics - Extra hot mocha - Coffee & Tea Near Me - Burlington, Vermont

What an incredible coffee shop! The staff is so helpful and helps you decifer their menu of various coffee drinks and roasts. I opted for the specialty latte - Sesame Seedzn, which had orange blossom, cardamom and orange sesame. It was amazing and so unique! It was lightly flavored with orange flavor. My boyfriend got an Americano and they let him choose the type of espresso in the drinks based on the varieties on the menu. He chose one that had grapefruit and cocoa notes - it was really good and not bitter at all. We enjoyed our drinks in the coffee shop, which was comfortable. There were plenty of tables and chairs. If you enjoy a good cup of coffee or a unique latte, give Onyx Tonics a try! read more

The coffee selections and information provided is awesome. Very informative and gives the same vibe as a wine bar with tasting notes and pairings. I am bummed I did not get to spend a solid couple hours doing a little tasting flight or talk with the two workers more. The selections of drinks were great and as said above the information given was awesome and any coffee lover would love to stop bye. read more

A Focused Espresso Haven for Coffee Purists While strolling around downtown Burlington, we stopped by Onyx Tonics. From the moment you walk in, it's clear that this place is all about focus--specifically, high-quality espresso drinks. As an espresso lover, it was a 5-star experience for me. I got to choose from the available bean options, each with highlighted taste notes, and my espresso was perfectly brewed and absolutely delicious. The attention to detail and quality is evident in every sip. However, the reason I'm giving it 4 stars is that my friends, who aren't as into espresso, found the place less approachable. They didn't enjoy their drinks as much, which made it clear that Onyx Tonics might not be for everyone, especially if you prefer sweeter or more familiar coffee options. If you're an espresso enthusiast looking for a carefully selected and meticulously brewed cup, Onyx Tonics is an excellent choice. Just keep in mind it's more geared toward coffee purists than casual drinkers. My Criteria: 5 stars: The best food I have ever had, or an excellent option given the price. 4 stars: Good food, a restaurant I look forward to trying again. 3 stars: Good food, a restaurant that I am indifferent to. 2 stars: Below average experience, will not go again. 1 star: This restaurant should be closed. read more

Has to be among the best places in Burlington for coffee. It has a pretty small selection, but these are from ethical sources and better quality. Onyx Tonics has okay prices for these. For once it's not a ripoff for some brew. There's also a few pastries and sweets. Came here in the morning because I needed perked up after the crazy night before. It's a pretty cozy looking place. There's the counter to order, and then there's a few tables. Check out the descriptions of the coffees. The sources and tasting notes are listed on the walls. It's about $3 for the Galactic Standard Blend. This has notes of apples, cocoa, dried cranberries, and warm spice. A little of a fruity flavor to it. The flavors change a bit whether it's served cold or hot, so read about what it ends up to be like. Get some ethnically grown coffee. It's not bad prices for as good as it is. There's also doughnuts but these aren't vegan, but even so, these looked pretty good though. read more

Very good coffee. Spare and clean cafe with a different vibe. Nice range of drink options including choice of beans. Not many Germans will appreciate the one off-putting moment I had when I asked for cream they told me they don't recommend such things for their drinks. No other offer to provide steamed milk (which was available). So I indulged them in tasting their product. I wish there was cream for my espresso. But, cortado works too. read more

The best espresso and tea for tens of miles around. It's been hard to find a decent loose leaf tea in a cafe for some reason. I've never seen over 20 types of espresso to try. read more

One of the best espresso-based coffees I've had in the US. It's up there with the top coffee spots in San Francisco and nearly as good as Australian coffee. A quick glance at the descriptive menu reveals that Onyx views coffee-making as an art form, and drinking coffee as an experience to be savored. How it should be. read more

Nice guys who made very good recommendations. Enjoyed our coffee and conversation. Highly recommend!

Yum! I got a pour over with Kenyan Beans, and it was delicious and wonderfully floral made using a hario switch. For weird coffee people this place does a good job. There is a bunch of beans that are on rotation, and brewers around too like aeropress, chemex, v60. Jazz music and good lighting for people that like to work at coffee shops or just want to read. read more

Such a cute coffee spot. Walked from the Hilton, not far at all, to this place, and I was excited to try the Maple Latte. I added an extra shot of espresso, and it was so tasty. I was given the option of oatmilk or local whole milk, and I went with local whole milk. read more

Got a really excellent Americano here. I ordered it with milk, which they served on the side. Out of curiosity, I tasted the coffee without the milk. Wow! Wonderful coffee. I enjoyed it so much that I ordered a second one. Too bad I'm not a local--I'd love to have a coffee shop this good at home. I was here shortly after they opened on a Saturday morning, and it was quiet for awhile. I got a lot of work done on my laptop. After a couple hours it was totally packed though. Just be prepared. read more

Great coffee spot! It's a chill spot that serves light bakery items as well. We were visiting the area and read great reviews about Onyx Tonics, and decided to try it out. "The coffee was quite literally the best coffee I've had in my entire life, and I'm from Portland, Oregon," what my girlfriend said. I'm a coffee enthusiast, and this was by far the best coffee I've had. The service was great, and we sat and enjoyed our coffee. read more

This was the best coffee we had while in Vermont. The iced Big Easy was phenomenal. I don't know what was in it, but you have to try it, it's an experience. I got 2 of them while we were in Burlington. The shop itself is really nicely decorated as well as clean and quiet. The drip coffee was excellent as well! read more

Incredibly good espresso, very knowledgeable staff. Not the lost approachable place - it looks and feels incredibly pretentious, but the staff are very approachable and personable and make you feel comfortable. My espresso was under extracted and therefore a bit bitter, which is the only reason it dropped a star. Very cool place. read more

Good place! Cute simplistic bright modern place. The oat latte was really yummy. I feel like this is a great place for people really into coffee (e.g people who like trying different espresso based on aromas). I love coffee, but don't have that type of knowledge, so it was a little intimidating lol. read more

A recent find for me, and if you're going to spend $5 on coffee - spend it here. Sure, you could get a SomeAChino mass produced that tastes like aliens dropped it from space. Or you could come here, where the guys have somehow captured the magic of time everlasting and focused it into handcrafted magic bean juice... my personal favorite is the Big Easy. It's a blend of chicory and coffee, like my mother used to drink and like you get at Cafe summer Monde in NOLA. Earthy touch in a balanced brew with a maple pop. Excellent. I'm not sure how they do it, to be quite honest, but the array of carefully selected coffees, specifically roasted to highlight the aromas and flavors is out of control here. They've got a small shop, just outside the heart of downtown with maybe a dozen tables yet somehow it's never "too busy" for them to walk you through the perfect cup. They have partnerships with local bakeries that lets you snag perfect little cakes to go with your coffee as well - you really can't go wrong. As a guy who drinks more than a few cups of coffee every day and has for the last two decades, this is a spot worth hitting. read more

Onyx Tonics - Can't miss the marker! - Coffee & Tea Near Me - Burlington, Vermont

Came here for breakfast with our kids but this place seems more of a hipster coffee shop so there weren't much food options for our kids. We got some baked goods that were already wrapped up on the counter and they warmed it up for us. I got my kids hot chocolate and my husband got the coffee while I got the maple latte, which was really good. There weren't many seating options and while we were standing there waiting for a seat, our barista kept telling us to go sit down and he'll bring it to us. However, there were no seats. Finally, someone got up and left the table open and someone who just walked in with their family sat right down and walked right passed us. Again, we stood for a good 5 minutes before someone else left and we finally got a table. The coffee and lattes are really good, love the art on the wall and the vibe here, but the lack of food options and seating made it lost a star. read more

I let this review lapse a bit too long. But our time here was really fantastic. They had multiple espressos on bar and the service was GREAT.

If you are a coffee snob, then this is definitely worth hitting up while you are in town. read more

Favorite coffee shop in Burlington & one of my favorites in the country. Really knowledgeable staff & incredible coffee.

We stopped by here as a quick place to warm ourselves up from the breezy outdoors in more than one way. The cafe itself is quite cozy, with a small area in the front to order and await your coffee (or anything else you may have ordered), with a number of wooden tables in the back of the store. Although there aren't windows, there are a lot of paintings of celebrities mixed in with a number of pooches wearing hoodies - an interesting combination to ponder while sipping on my beverage. Once did not have to wait up front; the folks were able to bring our drinks and snacks back to us. I will say that this is a very nice place to work (a lot of folks had their laptops up), although our little group probably detracted from it as we were a tad above everyone else's volume. As for the food and drink here - it was relatively good, with the drinks probably being a bit higher up on the list relative to the food. I really enjoyed my maple steamer, which was light and had an overtone of maple that was neither too sweet or overbearing. My wife's tea was quite good, and even if it was not served in more traditional Asian-style teaware, I did like the modernist teapot and glass they were served in. On the food front, we decided to sample a handful of the donuts on display. The donuts were potato-based, making them a bit denser and less sweet, and while this worked well for the cider donut (as apples can fall on the less sweet side of the spectrum), the donuts with berry frostings were a bit more distinct and didn't work quite as well, with the kiwi berry in particular being very tart and a bit dissonant against its base. While the donuts weren't my favorite, I did enjoy the beverages sampled, and with a chill vibe and a good selection of beverages, Onyx Tonics is a good place in downtown Burlington to take a load off or get some work done in peace. I'll plan on making a stop by next time I am in town! read more

Nothing like being told how you should drink the coffee you're paying for. They wanted to put a bunch of milk in the coffee I was ordering. Told them I don't like that much milk in my coffee and wanted less. The response from the guy behind the counter was, "That's not the way we do it here". Keep the coffee, guy. Later. read more

This is my very most favorite coffee shop in all the land; I'm here most every day. Things that make this place tops for me, in no particular order: - The variety. Three different bean options for espresso (and three for hand brew) makes for a CYOA experience. - The rotating menu. As a human, I delight in novelty. As a human with anxiety, I tend to forgo that delight for the comfort of the familiar. When the familiar is removed, delight is foisted upon me. - The staff. Are knowledgeable of their craft and full of the secrets of fine brewing, much like alchemists. Unlike alchemists, they are glad to share what they know with the uninitiated (I am the uninitiated). - The space. I mostly like to sit up front, where the light is prettiest and I can look at the plants. - The treats. There are a few local bake shops that provide the treats in the pastry case, depending on the day. They are all worthy. read more

I came expecting it to live up to the hype, but potentially due to COVID, my drink choice, or perhaps the combination, I left extremely disappointed. All seating is blocked off due to COVID, which was absolutely fine, but the staff was not overwhelmingly welcoming. I tried their signature VT Big Easy, but ended up pouring my $5 coffee on the grass after two sips. Tastes a bit like cheese mixed into coffee. I will have to come back to try their Maple Latte in the future. read more
