Hadanwonjeongjip is a restaurant in Busan that serves seoksoe bulgogi and gopdori tang. The seoksoe bulgogi has a strong smoky flavor, and the gopdori tang is a spicy soup made with chicken and gopchang. Because the tables are small, the gopdori tang is brought out when you are almost finished with the seoksoe bulgogi, and it is prepared all at once if you ask for it. The gopchang in the gopdori tang has a smell.
