Hormone Chichi Busan Seomyeon is a yakiniku restaurant in Seomyeon, Busan, serving beef and other meats. The charcoal fire is strong, so fatty cuts flare up and produce heavy smoke, and diners control the heat themselves. All orders are placed on a tablet, and there is a 90-minute time limit. Tablet orders come out slowly and may arrive as a different meat than the one ordered.
