I've had Jim's and Pat's, but found Pat's (the originator) to have a better cheesesteak. IIRC, Jim's uses top round, while Pat's uses ribeye. Besides, there's also that fantastic Italian market in the neighborhood. The best soprasetta and aged provolone I've ever had was from one of those shops.
But you're correct: the essential ingredient missing in Chicago is the bread. Because there ain't much to a cheesesteak: Bread, thinly sliced beef, Cheez Whiz or provolone. That's it. If you like yours "with" (like I do), add onions. 'Course, there's a million variations, but that's all you need for an authentic Philly cheesesteak. I've made them here many times, but I have yet to find the right bread to go with the sandwich.
