This place has been mentioned before, but it bears repeating. We just had an outstanding lunch there for about 12 bucks for 2 of us. I had a felafel plate - 4 delicious felafel, and it comes with a salad & sides of humus & tabbouli, which I shared with my husband. He had a shwarma sandwich and the felafel that I couldn't finish. All foods are fresh and perfectly seasoned.
It's on Washington, just west of Hill, and is right next to a used cookbook store (which is actually open occasionally).
