Dark Matter Coffee - Osmium Coffee Bar

Top shelf coffee roasted by over of the best Roasteries in Chicago, and brewed with exceptional care. Custom crafted lattes are well thought out ... and ... well ... Delicious! Staff is perfect neighborhood friendly.

Great atmosphere and drinks and food. Psychedelic art on the walls and tables outside gives it a completely different vibe than your typical coffee shop: something like 90s cartoon meets 80s movie secret hangout.

Please start taking names for orders and if possible, print tags showing name of item and name of customer. Discussed this with Barista and they agreed.

Great coffee and good food too. The coffee beans themselves are amazing often with floral and nutty notes. They are more expensive than your average bag of coffee, but well worth the price. The best feature of this place is the iced coffee on tap and the ability to fill up growlers of the iced coffee at a very affordable cost. The chocolate city is the best iced or cold brew coffee I have ever had. It is triple brewed so it packs a caffeine punch, drink in small portions.

I had an amazing experience here! I came in after a run wanting some coffee & the barista helped me decide which drink to get. I went with the wake & bake and it was amazing, definitely a great drink if you prefer flavored coffee that isn’t super sweet. I can’t wait to come back& try more!

The staff are always friendly and the drinks are always made with love. There's great music playing all the time with sick art on the walls. The have sandwiches, dessert, and amazing coffee. It's a chill spot with good vibes. Definitely check this place out. P.s. tons of seating on their patio too.

Okay they have Dark Matter Coffee (obviously), empanadas from Cafe Tola, and DoRite donuts. They also get bakery from West Town Bakery, try the herbed goat cheese croissant. Heaven on earth.

Very busy today, a Sunday afternoon. The coffee is frequently very good. They have a lot of options: pour over, press, drop, and the typical espresso drinks. They sell bags of whole beans, and can grind them for you. The service was friendly. Pretty standard pricing. They have outdoor seating behind the main indoor seating area. Standard baked goods selection.

Coffee was PERFECT. The Unicorn Blood Espresso was amazingly smooth and and not bitter or burnt. The Agave mixed drink and Latte had very different flavors, but both were very complimentary with the brew. Neither was overly sweet, both were delicious. The environment/art work/lighting was dark and disturbing, and the customer service was poor (no assistance ordering/offering a menu/describing sizes or costs - didn't tell me when my order was ready - bought a bag of beans, but had to return them for a more recent roast etc)

Definitely what you’d call a hip cafe with its own brand. The latte was pretty good but probably not a full 5 star. It was pretty crowded with many people spending time and working there.
