Always busy around dinner time so you should really go early or late at night if you don't want to wait. I usually get the kobideh (spelling?) kebab thing. They give you a generous portions with rice, salad and broiled tomatoes. All for $10 and I can barely finish it all. The meat itself is cooked over charcoal bbq with the fanning technique by hand!
It's a small place that's meant for takeout. The food is claimed to be low calorie and it tastes pretty damn good too!
