I never went to Pat's or Geno's. The whole Cheez Whiz thing was gross, IMO. I like 'em with provolone, mushrooms, salt and pepper - no sauce, no processed cheese food, no veggies...
Cook the steak with the cheese and the mushrooms, dash of S&P, slap it on an Amoroso roll... It was a lunch fit for a king at $1.25. I had a two-year love/hate relationship with Philly.
