That and the fact you can get Boars Head meats. WaWa is very good as well. Subway puts like 3 slices of meat. May as well just hand you the roll. And, they are hoagies, not subs.
For cheesesteaks like in Phila, try Philly Phlava. They get their rolls (Amoroso http://amorosobaking.com/) and meat from up north.
