Bun Patty Bun

Bun Patty Bun is a burger restaurant on the fifth floor of The Hyundai Seoul in Seoul, serving handmade burgers, french fries, and beer. It uses grill-toasted buns with beef or chicken patties, and adds tomato, red onion, and romaine for crunch. Orders are placed after finding a seat in the open food court, and only ketchup and mustard are provided. On weekends, there is a wait.
