Dark Matter Coffee - Osmium Coffee Bar

Phenomenal coffee and ambience. Everyone has told me to visit this coffee shop and it did not disappoint. The iced coffee they have on tap is delicious and the specialty barrel aged mocha latte hit the spot. Will be returning soon!

love this coffee shop! staff was super helpful and the decor was really cool. i drank the one with ginger and it had a taste i never had before, and not in a bad way! it was more bitter but also smooth with a hint of sweet

This place is incredible! I had the agave latte and veggie/egg breakfast taco and both were incredible. The agave latte had the perfect amount of sweetness. The taco was huge and kept me full all day. The ambiance inside the place is super cool — art on the walls, light up signage, and canned cold brew for sale just to name a few things. Will definitely be back next time I’m in Chicago.

This was one of my stops I had to go to while in Chicago and it didn't disappoint. The staff are friendly and service was excellent. Coffee was fabulous and I just really enjoyed my experience there.

Highly Recommend: coffee drinks here are really good. Have not had a bad drink here yet. They do get busy and for some reason the line sometimes moves really slow at the checkout probably because whoever is at the checkout sometimes pours drinks and gets food right away, but once order is in they make the drink pretty fast.

Great coffee, really wonderful specialty lattes. Will get you the caffeine fix you need, and is a great place to sit and work or pop in for a quick to go coffee! I usually am between the agave latte and the Mayan mocha

OMG this Chocolate City iced coffee is outstanding!! Smooth, flavorful and at a great price. Nice decor and a decent amount of seating inside. Loud music, but I visited on a Saturday so it may not be like that all the time. Great patio in the back with several picnic benches (it’s super quiet back there and there’s a few outlets).

Great place. It gets busy fast. After I got in, like 20 people showed up. It looks like they rotate through their flavors, so read the menu. It's really cool looking on the inside and they have a patio out back. All of their coffee looks delicious so I definitively need to come back again.

Nice and not too crowded, there’s an outdoor area at the back with plenty of outlets and additional seating. I got the Mayan mocha latte, which was spicy when I swallowed it, but it was a nice punch

Omg! So freakin’ good! Reasonably priced, adorable inside, great atmosphere, and awesome coffee. Looking forward to coming back here :)
