I am a fan of this place, and its a nice quick and healthy meal.
Granted, if you are looking for an authentic Mediterranean or Greek pita/gyro eatery, then this is not for you. This is a very Americanized pita place. I can probably best describe it as the "Subway" of pita shops.
Personally, I think the choices are great. They have a lot of "pre-made" pitas that you can order from, but I tend to always order freestyle. So far I have enjoyed everything I have asked them to shove in that Greek burrito. (It ends up looking like a burrito in the end)
Their hummus is good, and I am not sure if they make their own pita chips in-house or they are shipped in, but they are very tasty as well.
All in all, it is a great place to get a healthy tasty meal without costing too much.
