15 Coffee Shops Open Late In Chicago - Chicago - The Infatuation

"Osmium is one of the spots owned by Dark Matter Coffee, (who also own Star Lounge, which is open until 9pm). Besides serving excellent coffee, this spot has a bunch of creative coffee-adjacent specials, like a barrel-aged mocha and the “wake and bake” latte with maple, sage, and black pepper. There’s also a patio outside, but you’ll probably want to sit indoors where you can gaze at the artwork on the wall and wonder to yourself whether Salvador Dali painted it in a little-known steampunk phase." - veda kilaru
