Dark Matter Coffee - Osmium Coffee Bar

Great coffee and atmosphere. Got beans to go. Looking forward to going back when in Chicago next time.

The coffee was pretty good [for me], the service was not. We had to flag down the barista, even then one of our hot beverages got to us lukewarm. Lucky for me it's not my local cafe, so I needn't worry about returning. The murals are great though, you should check out Jason Brammer's work online.

The coffee is delicious. I got the cold brew flight, and loved being able to try all the variations of cold brew they serve...great idea. Anytime I need a coffee present for someone I always come here for their great selection and helpfulness.

Overall good vibes to be at. The mocha was alright though. I would try something else next time I'm there.

Pretty delicious coffee and specialty latte selection in an awesome bar-like setting with great music, an awesome vibe and laid back, fun staff. Great spot to get in some wi-fi but the connection is a bit screwy at times.

An amazing local coffee shop with fantastic baristas looking to make tasty and beautiful drinks. They have a wide selection of food as well. It’s a great place to get a coffee to go or stay awhile and enjoy it at your leisure. Highly recommend to anyone passing by on Belmont!

Great coffee but obnoxiously loud music that makes this place very much feel like an anti coffee shop. It was like being in a nightclub and everyone is shouting to be heard.

Coffee was alright, had one of their specialty cold lattes and a hot latte but wasn't really impressed. Quite a few other coffee shops around Chicago that have impressed.

Best cold brew I had during my trip.

The staff here was very kind and attentive! Coffee was great as well. Note: they check for your vaccination card :)
