OK...have to ask...are you from Mayfair or Frankford?
I grew up a few hundred feet from Greenman's, so Hoagies were set in the taste buds once I could eat solids! Steaks were usually from a place 2 blocks away (Mark's at that time) and always a PIZZA STEAK...for me with sauce, provolone and onions. (LORD, now I'm hungry...!)
Moved away in 1973 and in trips back I found that the Cheez Whiz abomination had taken root all over.
Back in my youth, though, not all neighborhoods had or had even heard of a Pizza Steak.
No, there were no pizza steaks back then - think they started in the 70s, maybe even 80s.
The only time I remember running into the cheese whiz thing was one night probably in the late 80s we were headed to a Phillies game and decided to stop in South Philly for steaks at either Pat's or Geno's. First I ever saw cheese whiz outside of a supermarket, and, no, I didn't get it.
