Pita Heaven is literally my heaven. I have only ever eaten the chicago gyros, but they are d.i.v.i.ne. The perfect mix of grease + quality lamb. I have been to other places where the gyros seem to be a little too roasted, or seasoned, or "quality," but the lamb here did not taste like anything out of the ordinary.
I often call in my order, and they have it ready within 5 minutes. THeir fountain drinks are also MASSIVE and STYROFOAM.
The only reason I didn't give Pita Heaven 5 stars is because I am stingy with my 5's and have a hard time giving one to a "not-so-fast fast food" place. But between you and me, it is a 4.75.
