9 Restaurants That Could Only Exist In Philly

"In South Philly, Mexican and Italian communities live in mass. So, in a way, pizzas layered with mole and quesillo are an obvious innovation. (We wrote a whole guide about them.) Of all the options in Philly, Rosario’s simply does Mexican pizza best. Instead of getting hit with a waft of steaming marinara, these thin, crispy pies will smack you with cilantro, lime, and sizzled jalapeños. We especially like the version with al pastor or the avocado- and sausage-topped Mexicana, both of which are good enough to shout about from the Philly mountaintops, also known as One Liberty Place." - candis mclean
