As a native Pittsburgher, I'm slightly embarrassed by how long it took me to finally try one of the various Peppi's locations. But once I did, I went every week for a month. I don't go nearly that often, but I love the friendliness of the staff along with the selection of mouth-watering sandwiches. I don't know what they put on their meat. I don't know how they found the perfect bread for subs. All I know is that it all keeps me coming back.
I've tried several variations of the cheese steak and I've had the Italian sub. The fries are average, not my favorite and no something I even feel is necessary with the Peppi's sub. When visitors ask me where to get a good sandwich, I'll recommend Peppi's or Primanti's. Though anymore I favor Peppi's for myself.
