I'm not sure if the Phoenix area has a sizable Persian immigrant population or whether the tiny numbers are just all at Persian Room, but I was surprised to see what looked like an authentic restaurant in a suburb on the edge of the desert that is far more concerned with money than even the semblance of diversity.
Since this was my family's first experience with Persian cuisine, we went with samplers all around. Coming from someone who appreciates the food, standouts were the eggplant hummus and the fesenjan I snuck in on the side.
I wish I could tell a story of redemption and enlightenment about how they came around to the variety of tastes but since they hate rice, flavor and change the results were somewhat predictable and this visit was likely ill-advised from the start.
The Persian ice cream (flavored with pistachio et. al.) was one of the few things to gain universal approval unlike the only actual miss of overly sweet baklava.
For huge plates of grilled meats, sizable varieties of rice, stews, fresh breads and subtly flavored sweets and everything else one would expect from Persian cuisine, especially in this area it's difficult to go wrong with Persian Room. Lacking a superpower that allows the instant digestion of grains, come hungry.
