First time I went to the Pita Shack was last summer and they didn't have the air-conditioning on, very uncomfortable.
Last week I gave it another shot, figured it was cool enough outside to be safe. Good thing, because no AC again. I got half way through my gyro and bit down on a small bone, cartilage, or something else. It freekin hurt my tooth. I didn't complain or anything, I just won't be going back.
Too cheap for AC, they probably cut corners with the quality of there food too.
