At Nokaneun Hambeogukuyo Shinsaibashi, diners grill hamburger steak themselves on a hot iron plate. After cooking the patty to their liking, they finish the meal by frying the remaining rice with garlic chips and garlic salt. The restaurant opens at 11 a.m. and orders are placed by QR code. Oil splatters heavily from the iron plate and the meat smell clings to clothing.
