In reality, there are few places that make it right. The one place I liked in LA (run by a brother and sister from Philly) was killed by the lockdowns.
The best Philly cheesesteak I’ve had was about 40 years ago — in Philly. My (then) father-in-law was a Baptist deacon and you never EVER even walked into a bar.
But he’d break his own rule sometimes to pick up Philly cheesesteaks to bring home.
Something else I had there that I loved was something I’ve only seen one other time — in Anchorage. IIRC it was in a hoagie roll, eggs (scrambled, I think), green peppers, and onions. It was delicious.
