Having never actually been to Philly I can't vouch for the authenticity of these cheesesteakes.
What I can vouch for is their supreme deliciousness. I ordered mine with "The Works" (shaved steak, provolone, onions, mushrooms, green peppers, topped with cheese whiz) and DAMN BITCH, that's a tasty sang-wich! Slightly greasy, rather messy, and so good.
The friendly staff also offered us a free sample of their new creation...fried boneless chicken coated with crunchy frosted-flake breading smothered in sweet/spicy sauce. Awesome!
I'll be back to Philly, fo sho.
