Philly Cheese Steak Sandwiches

I was in Philly once.  I didn't eat a cheese steak.  I don't know why.  Oh, yes I do.  Its because I drove right through without stopping.  Dumb move.  Next time I'm in Philly, I'll eat a cheese steak.  Until then, I'll just make one of these.  Unless anyone knows where to get a good cheese steak around here?

I used london broil cause that's what I had.  I think a thick rib eye is the preferred cut of cheese steak enthusiasts, but don't quote me on that.
