Think of this as Subway for pitas, only much better. Personally, I love the fact that they have multiple vegetarian/vegan options, including labeling which sauces are free of gluten, dairy, etc. Also, you can get smashed avocado on your pita for no additional cost (at this location, some differ). At Subway, that is a $2 upcharge.
I first fell in love with Pita Pit in college, 20+ years ago, and now I go there because it is that rare restaurant with healthy and tasty options.
