First, you need to try a classic cheesesteak sub . You can find them, of course, all around the city, as well as in the famous Reading Terminal Market (another must-stop for a foodie tour of Philly). Jim’s Steaks (on South Street) is a local favorite. Philly also boasts amazing soft pretzels, pizzas (try the square pies, like those at Santucci's!), and scrapple, a crispy-fried breakfast dish made of pork, cornmeal and spices.
