I have been to pretty much every place in Philly known for their cheese steaks and Those Guys Pies has it right. Only place in LV offering whiz that I know of. They offer provolone and white American as well.
The pizzas are awesome too!
Plain cheese and the meat are my favorites.
Did I mention they deliver?
You cannot go wrong with this place for a pizza or cheese steak. Well worth the drive.
