Philadelphia is known for cheesesteaks and hoagies. The reason why you can't find either outside of Philly is because of the bread. It's a specific brand and truly makes the sandwich.
WaWa originated in a Philadelphia suburb. The bread they use for their hoagies, while not the same brand, is a very close second. I'm not sure about the quesadillas, clubs, burritos or pitas. I never had those when I lived in Philly.
The bowls don't have the bread, so you are not getting the "Philadelphia Experience."
