What 1,070+ diners say about Dark Matter Coffee - Osmium Coffee Bar

Barista and staff helpful and insightful. The drinks and atmosphere were unique and amazing. I bought a bag of Chronica and Fuego, both are great. The mayan mocha and wake n bake are amazing drinks and not something you'll have often. The shop and the drinks were some of my favorites in the country

“Beautiful artwork, indie music, and killer coffee.”

Beautiful artwork, indie music, and killer coffee. Wish the WiFi was better, had to connect to my phone

“Great spot to work and chat with friends.”

Great spot to work and chat with friends. It gets busy but that only adds to the atmosphere. The espresso was top tier and their agave latte was surreal. The wifi is super good as well. I really enjoyed this place! My only comment might be about the waiting process, you need to be alert for them they call your order. Since the place is loud and busy, one might not hear it the first time. So keep that in mind. Overall, great experience.

“Dark Matter never fails to impress me, especially at this particular location.”

Dark Matter never fails to impress me, especially at this particular location. I really appreciate that they stay open late, which is perfect for someone like me who enjoys a good coffee at unconventional hours. The consistency of their drinks is unmatched—a rare find for a coffee connoisseur like myself, as other places often disappoint in that regard. The staff here are incredibly friendly and welcoming, and their prices are very reasonable, especially considering the quality they deliver. If you’re looking for recommendations, my go-to specialty drink is the Iced Agave Latte—it’s absolutely phenomenal, and I can’t recommend it enough! You have to try it for yourself. Don’t forget to grab a loyalty punch card when you order! Just another perk of Dark Matter.

“I couldn't help but to give this place all perfect stars.”

I couldn't help but to give this place all perfect stars. The gentleman at the cashier has a very kind and of aura and the barista person is wonderful at his craft. The herb and goat cheese and herb croissant tasted wonderfully even with my simple latte. (My sister had tea and she loved the rich earthy and naturally sweet flavors) The music is just as comfortable like a light-hearted festivities. I love sitting at the bar, which is for certain one of the most comfortable I found in any coffee shop. And the mural has such a beautiful balance of cool colors with the right amount of drama from the uneasy red. I highly recommend stopping in even for a simple coffee break from exploring Chicago.

“One of the best coffee shops in Chicago with arguably some of the best coffee to offer anywhere.”

One of the best coffee shops in Chicago with arguably some of the best coffee to offer anywhere. Incredibly dark, creamy, aromatic espresso with a great selection of freshly roasted beans. Lovely interior with some really cool artwork. Plenty of seating with a nice outdoor patio area in the back. Super chill vibes

“We really enjoyed the draft coffee options — both the Vanilla Suburbs and Black Splash were tasty with nuanced flavors.”

We really enjoyed the draft coffee options — both the Vanilla Suburbs and Black Splash were tasty with nuanced flavors. The service was very friendly too.

“So glad this is in my hood.”

So glad this is in my hood. Their cold brew is the best in all the city and has spoiled me and heightened my expectations for all others. Chocolate city baby!!! Their regular hot coffee is excellent as well and I always get beans from them - Love Supreme is great as a pour over. Try their other roasts - all unique. Place is v chill if you go at the right time. They get very, very busy on Saturdays between 9:30-11:00a. Their crew is awesome. Couple of them have been there forever and they’re awesome. Thanks y’all!

“This place is so chill.”

This place is so chill! The vibe is relaxing and the open concept is great! I got the cinnamon twist danish and the Barrel Aged Mocha! As an avid coffee drinker, these are the STRONGEST drinks ever. Do not try to pound this drink, they are sippers! But a great place and love the energy!
