It's a small space with a little front patio and a few seats inside, but it's nicely appointed and clean with a lot of decorations and Ethiopian crafts and art, including some coffee sets from the country -- you just get a nice, warm feeling there. The staff is friendly as well.
I got an iced coffee which hit the spot, and while they don't have sandwiches or bigger fare, they do have lots of pastries and such to snack on. The coffee is, I believe, mostly from Ethiopia (Harar is a coffee region there.)
The spot gets good reviews on Yelp too, and is open until 7 or 8 pm everyday, which is great. If I lived closer, I'd definitely go there a lot.
They're at 2904 Georgia Ave NW, open Mon-Fri 6am-8pm, Sat 7am-8pm, and Sun 7am-7pm. They have a Facebook page too.
