Looking for somewhere to eat downtown? Philadelphia's first (and currently only)Certified Green Restaurant by the Green Restaurant Association (GRA) is officially the Pita Pit, located at 16th & Sansom. I fell in love with Pita Pit at Penn State's location (We are!) Their speciality is pita sandwiches, a healthier alternative to fast food. I was psyched to hear they went green and wanted to learn more about it.Looking for somewhere to eat downtown?
