I can't attest for the bad service, but I could see that happening, they're severely understaffed and those that work there seem young. That being said, I will give the 4 stars on their food and ambiance, really the food is 4 star food for the price point in my book.
I don't know if I've just not had Turkish, but the food here is awesome. Everything is recognizable on the menu: schwarma, lamb shank, hummus, falafel, etc... but when it comes there is always a deliciously different taste to the food.
The baba ganoush is smokey, the falafel is served with a oniony cucumber sauce, and on and on...
Give this a shot. Strong, yummy flavors in a relaxing, causal environment. Come early for good service? Dunno.
