I had to stop a Primanti Brothers for one of theirs. It is in the warehouse district and supposedly the sandwich is made so that the working guys can eat a meal with one hand and push a hand truck with the other. That means that when you order a sandwich you get it with fries and slaw on it. My cousin was telling me that a local custom is to take an out-of- towner down there after midnight. (they are open 24 hours) If they can get the guy to go in wearing a tie somebody from the kitchen wearing a bloody apron shows up and cuts it off with a cleaver. Sounds like fun if you are not the one with the tie.
