I am a big fan of Pita Jungle. I visited the Tempe location while attending ASU and was extremely happy when the Gilbert location opened. The food is great, the servers are attentive, and there are always great pieces of art work on the walls.
If you have yet to visit, I recommend the Jalapeno Cilantro or Roasted Bell Pepper Hummus. If you want to try both, be sure to ask for half n' half and ask the server for the Greek pita or cucumber slices.
There is one downside to the restaurant and that is the location on a busy Friday, Saturday, or any other busy night. Park away from the entrance so you are not circling for a spot and/or waiting to be seated.
