Pita Pit is my lunch of choice when I am too lazy or crazed to bring in my own food for the work day. The interior is clean, the food is fresh, and the service is always friendly.
Now if you are heading over there during the work week, be sure to take note that this place is PACKED between the hours of 11am-1pm. Everyday. The line moves quickly, but you'll probably get jostled around a bit before ordering your pita. And if you don't work uptown, I imagine parking can be a big hassle, so this might not be the most convenient.
I always order the hummus wheat pita. It's delicious and they cram a ton of veggies into it (I literally choose almost every veggie they have, plus avocado, and there are no additional charges). The pita ends up being so large that I eat half for lunch and then save the other half for dinner. Two meals for around $6.00 is an awesome deal!
