Food was very good in my opinion -- I have a sesame allergy and they were easily able to accommodate it when I ordered bread and so on. I ordered lamb shank with dill rice and it was a very large portion -- meat was very tender and the rice was good, not too oily at all which I find is the problem with some other places I otherwise like. Yoghurt/eggplant dip is good but could use a bit more seasoning; I find it is good if you accompany it with some of the parsley/onions given with the appetizer. My father ordered a lentil stew which he said was very good. Salad shirazi is also excellent.
The atmosphere can be a bit strange though, there seems to be a very large part of the restaurant with big seating areas, I guess for big parties or something, and if you come on a slow night (I came early on a Friday evening in the middle of January, there were only two other tables at the time) it can look very dark and empty.
The waiter was a polite young guy. No complaints about him.
Overall I would recommend this place, esp for stews and so on --- the décor could use a bit of an update however.
