DO NOT waste your time at Pat's or Geno's. They are vile.
Go to Reading Terminal Market and get a roast pork sandwich at Dinic's. Also pick up some homemade chocolate and fudge at Mueller Chocolate Co.

If you want a cheesesteak go to either Tony Lukes, John's or Dellasandro's. All three are great.
