I've never been to Philly, but this is what I expect a traditional cheesesteak would be like. The loaded sandwich comes with an (un)healthy portion of meat and caramelized onions, in addition to the standrd cheez whiz topping. It's so greasy that you have to race to eat the sandwich before the bun disintigrates. Don't wear your finest clothes to eat this sloppy sandwich.
Protip: one order of fries is enough for a family, especially after consuming an entire cheesesteak. They're equally as delicious and greasy.
P.S. When you order a combo they give you a hot pepper with it. Yum.
