Philadelphia is now home to the world's longest line of cheesesteaks after vendors and partners at PHL set a Guinness World Record on Tuesday. Fittingly, the recognition comes on National Cheesesteak Day. The line of Philly's well-known delicacy stretched nearly 1,200 feet. After the award was given, the cheesesteaks were offered to airport staff and passengers. #PHL #nationalcheesesteakday #philadelphia #philly #guinnessworldrecord #cheesesteak
