I grew up in Philly and have tried every cheesesteak there. A little place called Dalessandro's beats everything on South Street. Now that I'm in LA, I'm looking for something that comes close.
What makes a great cheesesteak? Fresh bread that's soft on the inside but crispy enough on the outside that it doesn't fall apart. The meat is cooked fresh rather than pre-cooked or sitting on the grill waiting for someone to order a sandwich. Oh, and enough seasoned fat to make the paper bag see through and kill you moments after eating it. Fried onions, mushrooms and peppers that shine from the steak grease on the grill. Real white American cheese on top, not Cheese Whiz. Then topped with a tangy pizza sauce that would perfect any pizza.
It's a sandwich that's to die for (you probably will) but it's a great way to go!
Anything like that here in Lo-Cal? (Lower California)
Send out the hounds! ;-)
