Viking's Wharf COEX is a buffet restaurant on the second floor of the COEX Convention center, connected to COEX Mall and the subway. It serves lobster, beef galbi, grilled scallops, steak, hoe, mango, and desserts, and the lobster can be eaten multiple times. Waiting can occur at the start time, so a reservation is advantageous, and a chef cuts the lobster for you. Some of the food is lukewarm and the soup has gone cold.
