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

Cool vibe inside, the menu is limited. The speciality coffee selection it different than your regular coffee shop. It is rich, flavorful and grows on you as you drink it. You have to like it to enjoy it.

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

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!

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.

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.
