    Loved this coffee shop. Amazing, smooth espresso. Cute, modern, and plant forward decor. Super helpful service. 10/10 recommend!

    Galactic Standard Blend
    Steve A.

    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.

    Cold Brew

    Great spot with good coffee Pros: -Excellent cold brew -Reasonably priced ($4 for my cold brew) -A/C -Good amount of seating -Fast WiFi Cons: -Your standard coffee shop on the inside, nothing too special. But I will say the menu was very creative, so big points for that!

    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.

    Maple latte

    Maple latte. Great and friendly! Highly recommend. Dog friendly!!!!!!!! You will love it

    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.

    Iced Maple Latte with local whole milk

    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.

    Americano.

    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.

    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.

    Coronavirus life!

    Taking plenty of precautions during Covid, they have closed their indoor dining for now (summer 2020). They were super kind, quick and the maple latte was delicious. **flexibility being key during a pandemic**

    Big Easy - GET IT
    Rebeka M.

    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!
