My wife and I have been going here since shortly after they opened. The waitstaff/cooks/owners are all very pleasant, acknowledge us as soon as we walk in the door, and know what our likes and dislikes are.
The food? Perfectly cooked and prepared every time. Large portions for the money spent will always leave you stuffed, but I do recommend you save room for a piece of baklava.
Just to prove that I am not a total fanboy though, I sincerely wish they would provide more than a single pita to go along with their hummus (which is to die for), as there is always way too much hummus left at the end of the pita. Please, 2 pitas would not ruin your food cost.
Other than that, the food is fantastic, authentic, and inexpensive.
