Greetings from suburban Philly !
First, don't take cheesesteaks too seriously. It's a way of taking cheap tough meat, slicing it real thin (freeze it first if you're making one at home), and frying it so it's tasty and quickly made. IMHO, you can find a competently-made cheesesteak in almost any neighborhood from Atlantic City to Lancaster.
Though places near the tourist-attracting areas get most ink, I'd like to mention
Walts, on Baltimore Pike in Clifton Heights (in same location for over 50 years)
Mike & Emma's, on McDade Blvd (alt US 13), in Ridley Township,
about 3 blocks south of the PA 420 intersection
Larry's, on 54th near City Line, across from St. Joseph's Univ.
Good eating to you!
