Nope, I don't think I've ever been in a place anywhere in Philly / Jersey / PA that didn't have provolone as a choice. Another universal choice is American cheese.
In fact I think you'd have trouble finding Cheez Wiz outside the Philly city limits.
I hate to say this but when I was a little kid my mother had this Cheese Wizz stuff. I remember asking what it was, she couldn’t answer. Just said, it supposted to be good. To this day I still don’t know what it is.
