no one cares about Philadelphia. That's why it's Philadelphia.
So if we call it a cheesesteak your small world would be in sync?
Whoa, there nellie. No need to get hostile.
What I am advocating here is just a little "food purity". How many regional variations of pizza are there? From "Trenton Tomato Pies", to "Chicago Deep Dish", to "New York Style", "Neopolitan", "Sicilian", etc.
If you call a steak sandwich a "Philly", it needs to be made with fresh thinly sliced ribeye (no frozen steak-umms or steak-eze), and your choice of three cheeses. Cheez Whiz, American or Provolone. (Cheese Whiz being the favorite among the locals, but I like Provolone - which is still within "Philly" specs)
Put processed Swiss slices, bleu cheese, or whatever on it and it ceases to be a "Philly".
So yes, call your creation a "Swiss Steak", "Bleu Steak" or "Cotija/Avocado steak" or whatever, just don't call it a "Philly" because you muddy the waters when you do so.
I've had "New York" style pizza and "Chicago deep dish" pizza that looked and tasted like "pizza" I had a Chuck-E-Cheeses. What a disgrace!
In this area, when you order a "large pie" they ask "pizza pie, or tomato pie". Just a regional thing I suppose, and I don't give a rat's ass if you care about Trenton less than you care about Philadelphia, Chicago, or New York.
