I’m a proponent of this theory. Actually I’ve been relating a version of this to my friends for years, though my region was a bit more restrictive than this one. The gist is, the only good pizza is from a narrow area centered on the tri-state area on the east coast. It’s true, and if you try and tell me your Chicago deep dish matches up, I’ll wave a greasy sausage in your general direction and suggest you lack taste.
