★★★★★ 5.0 Jenny Mae Samson · Jan 2026

Excellent coffeeshop offering Onyx, Native, and a handful of other roasters. The new space in 220 is gorgeous - large windows so full of light, a few spaces to sit at the bar, and lovely baristas who do the craft well. I'll be back often.

I’ve treated myself to the coffee here a few times and when I tell you it is SUPERB QUALITY…it’s some of the best I’ve had. I usually run to Dunkin, of course, to save coins, but every now and again I switch up. I always get decaf when I drink coffee, and this is a mocha latte with oat milk. So delicious! They never disappoint! Everyone is nice, but JJ is THE BEST and one of my favs! Super personable, friendly, and efficient! She always treats the customers with respect, knows their names, and you can tell she really enjoys the interactions.

This is one of the first places in DC That has an actual flat white on the menu, AND It’s an actual flat white and not a latte! I could not believe the caliber of coffee I was having in the basement of the Cannon House office building. Absolutely terrific!

★★★★★ 5.0 Rebecca Thompson · Jan 2026

Add Common Grounds by Black Crown Collective to the top of your must-try list of DC coffee shops. Best brew, best vibes, and best service in town. If you claim to be a coffee connoisseur, get on over and grab a cup! It won’t disappoint.

★★★★★ 5.0 McKenna Simpson · Dec 2025

If I could give this place 20 stars I would. The best drinks, even better people!! Their matcha creations are some of THE best I’ve ever tasted. Seeing what they come up with each season is always a treat. The team never fails to make me smile and they truly care about each and every customer. If you’re looking for the best coffee in town, you’ve found it.
