Regarding above, there is a dividing line in PA .
Eastern PA it's a soda, hoagie, sneakers. Western PA it's a pop, sub, and tennis shoes.
And then it gets into subdivisions.
No real Eastern PA'er would ever allow lettuce, tomato, or mayo on a cheese steak. I have seen this abomination in Pittsburgh, I love that city, but may the Lord have mercy on their souls for that desecration.
Ditto hot Italian hoagies. Pittsburgh had them in the 1980's. I know Jersey Mike's pushed them earlier this year, but they're a chain and call them subs and have no real claim to hoagies as Eastern PA'er know them. Again, going back to the 80's
There are 3 things that PA does better than any other state. Hoagies, Cheese Steaks, and pretzels.
And I will die on that hill.
