Pffft.
Pizza (NY, not that Chicago shit)
Cheesesteaks (Philly)
Bagels (NY)
Taylor Ham (aka, pork roll; NJ)
The list goes on...
Don't get me wrong - The south owns BBQ, but the Yankees have made some good food.
Was about to cite a few of the above myself. Can't beat a good NY pizza or bagel. Also love me some chicken rolls and calzones. Always swing by my favorite pizza shop off Queens Blvd. when in NYC. Been going there since high school days. Chicago pizzza to me is like a damn pot pie, wtf, over?
