Gyeonghuigung is a shabu-shabu restaurant in Busan that has run for 30 years with regulars, serving sangchu-ssam shabu-shabu and mushroom-vegetable-beef shabu-shabu. Ingredients go into a distinctive broth: vegetables, tender meat, and chewy garaetteok. Staff serve the food rather than a self-service setup, and at the end you can add ssuk noodles, kalguksu, or porridge. A frog ornament stands at the entrance, and a car wash operates in the basement parking lot.
