...head down to the corner of Market Street and 19th Street (maybe 20th? I am not 100% sure), and stand in line at the Greek falafel street cart and you will get the best falafel in town. The vendor, a very talkative and funny Greek chef, runs a one-man show with all food from scratch and fresh, including marinated grilled lamb, chicken, and of course, falafel. There is fantastic grilled jalapenos, tahini, salad, olives, fleshy giant grapes, and on and on. All plates are made to order (and he makes everybody wait while he makes them, so the line is slow but worth it), and there is no menu. You just say what you want, and he makes it and you pay. Fantastic!
