Ledo Pizza: Maryland-based pizza chain, with locations primarily in the DC metro area. (The closest location to Philadelphia is Lancaster, although they seem to be expanding into other areas like mad.) Absolutely incredible pizza; great pasta and sandwiches, too. They are currently offering several cheesesteaks, of which I am suspicious. The South Philly Cheesesteak DOES look incredibly South Philadelphian though (I did not try it as I was feening for the pizza). And they have this other offering that I can best describe as a Primanti's-style sandwich-salad. (I can see folks in Pittsburgh screaming in sheer terror upon reading this.)
Their franchising system looks like a good deal too...uh-oh, I see another Career Option thread coming.
