In my opinion the Persian Room is the best Persian restaurant in the valley but not quite up to par with the Persian food available in Orange County and Los Angeles. I have been here a couple of times so far and always enjoy what I order.
We had dinner there last weekend and we ordered the Tah Dig appetizer with Fessenjen- picture a large platter of crispy rice topped with a stew of pomegranate and walnut sauce combined with chicken. This was probably the highlight of the meal. We also shared the Persian Room Special (a platter or rice, filet and chicken with two grilled tomatoes. The meat was quiet good but I find the rice to be somewhat lacking flavor compared to what I am used to. We had the saffron ice cream for dessert which was good but not super exciting.
I am sure we will be back as it is the best Phoenix has to offer.
