Hi - just had a fun dining experience at a fundraiser at a little club called Fluid (I think) at 1524 U Street NW (b/w 15-16th Street).
Fluid is an interesting retro bar/lounge w/ cool 50/60s tables with chrome on the side and those silly 60s fiberglass flaired chairs - they also have a red pool room with chrome hubcaps on the wall. Almost as an afterthought they happen to have a kitchen cooking Eritrean. As they told me, it's like Ethiopian only better. The food has nothing in common with the decor and at least on this night, the crowd except for a trio of regulars hanging out at one end of the Bar.
I tried the chicken zil zil and the tibisi (lean meat). The injera (bread upon which the communal food is served) was nice and spongy and fairly warm. The sauces were particularly good, very strong, spicy and hot. Eventually the spices were hot enough that I had to eat only Injera for about 5 minutes. The side of spinach and lentils was great. I'd say that they at least rivaled Meskerem and she gave me a break on the price - only $17 for a meal that served three (plus two others who had a small snack), basically she didn't charge me for the spinach/lentil sides. The entre's are $8 or $9 each. Coronas were $4 apiece. If you're out on U, it's worth checking out.
Oh yeah, they don't actually have a sign for "Fluid" out front. In fact I think that they have an old sign for another club. So go to 1524 and go downstairs to the basement (not up) and ask for the Eritrean menu and have fun!
