This restaurant is located in Iranshahr street, central Tehran. It can get crowded at times, with a line forming outside. For us took 1 hour to get in. There is only one item on menu that is Dizzi, a kind of lamb broth. Ingredients are lamb meat, lamb fat ( usually obtained form fat tailed lamb, from hind part of those lamb breeds), tomato, lime juice and fragrant herbs. Then they are mashed with baked potato into what is mashed lamb meat in Farsi ( Gooshte Koobideh), Also lamb broth is mixed with hot, out of oven, Sangak bread. Usually eaten and served separately. Your server can help with the prep. Condiments include onion pickles, Ahirazi salad, and Leete pickles ( Leete Torshi). End the feasts with hot black tea and Baamieh ( sugary sweet) substitute for shaver, see photos. Decor is traditional, with a lot of old style paintings around( see photos), hey are called tea house paintings. Service is fast, and efficient. Street parking is limited. Prize if each set including all included and tea is about 7$ per person which I think is a great deal. It’s an old restaurant and I think it is worth it. Curbside look is unpretentious, inside decor is nostalgic of past times. 👍🏼
