OLD CITY. What started as a small mom-n-pop grocery back in the 1940s has evolved into one of the signature places on Market to enjoy a Philly Cheesesteak. Is it the best in town? You be the judge. Just know that you're not going to find to find a friendlier place to enjoy the city's signature sandwich. If grilled rib-eye topped with provolone and onions doesn't strike your fancy, don't fret: They also serve up great hoagies and even a few vegetarian options.

SOUTH STREET. It's best to know your P's and Q's before visiting this South Street cheesesteaker, where the grillmen take their choice top round very seriously. At Jim's, all steaks come with onions (that's just how they come, simple as that); subsequent "extras" range from "Whiz" and provolone to roasted bell peppers and mushrooms. Hoagies, soups, salads and even a few breakfast items round out the menu. Even if you're not in Philly, you can still enjoy a bite from Jim's ­ They'll send a sandwich wherever FedEx delivers in the US.

SOUTH PHILLY. First-timers may ask, "What's an 'Old Philly Style Sandwich?'" The answer is right here, just a stone's throw from the I-95 over-pass. Tony Luke's has garnered accolade after accolade over the years, and its walls are adorned with the faces of celebs who've dined here and enjoyed every last bite of their Cheez Whiz-covered steak and Italian pork sandwiches. Of course, the place has never ceased to connect with its more blue-collared customers ­ the reasonable prices and good-natured staff see to that. The newer location at Rittenhouse Square makes Tony's fare a lot easier to get for those working in Center City.
