Go here, get koobideh and barg kabobs. Koobideh is ground, spiced beef and barg is like steak / carne asada. The best koobideh and barg consistently I've ever had in my entire life as Persian person and food lover, especially at their low price points. I would recommend washing down with fresh, not carbonated, yogurt drink with mint. They also have good yogurt + cucumber side and eggplant side. If you like rice, get rice with your kabobs.
The staff is also very nice!
