3.5 stars. I think my expectations were a bit too high, but I still enjoyed the food.
The menu is a bit sparse, but I understood after walking in that it is meant to be a fast-casual dining establishment. Interior is small and simple, but you can dine in if you so choose.
Service is fine, and prices are average. Food is solid, but I do wish they had more offerings. I just had Afghan food recently in Northern California, and I have had Persian food countless times, so it was difficult for me to pick out any particularly special dishes here.
