Primanti Brothers is a must try for visitors and a must have for locals. They have a variety of sandwiches served on two thick slices of Italian bread. They heat the meat and cheese on a grill and then add a vinegar based coleslaw and french fries to the sandwich. They are famous for their cheese steak sandwich, but I prefer the roast beef. If you want to add a few more calories, you can add a fried egg to your sandwich. They also serve side orders of fries and pickles. If you haven't tried it, I would recommend it.
