Rethink your definition of Philly Cheesesteak with a stop by this happening spot. Formerly food truck only, the Koja Grille now has its own permanent spot and an expanded menu. While plenty Korean and Japanese specialties are on offer, the signature item is the Bulgogi Cheesesteak, which combines spicy Korean beef with traditional cheesesteak ingredients and sweet chili oil on a hoagie roll.
