Jazzy Patty is an American-style handmade burger shop in Seoul that plays jazz, a six-minute walk from Exit 6 of Hongdae Station. The Classic is a simple cheeseburger with a bun, patty, onion, pickle and cheese, and the patty edges are cooked crisp using the smash method. The interior is tidy and food comes out quickly, with grilled buns served flipped over. The Jalapeno Bam adds jalapenos to the bun and patty for a spicy menu item.
