I've been here twice during lunch time - the second time to overwrite my first experience (since this is close to work).
The first time, the food AND service were terrible (very dry chicken wings). The second time, the service was exceptionally bad and the food good (the souvlaki wrap). I've found them to be short staffed (which is palatable if they're nice about it). Except, what you get is a blase, cold "deal with it" attitude which is very turning off.
If I really need to go back, I'll go for the souvlaki roll but get a take out instead.
