Oyster Express Oyoyoy is an oyster bar in Yeonnam, Seoul, serving raw oysters from Tongyeong and scallops. The raw oysters come with lemon or pair with white and sparkling wine, and the menu also includes fried oysters and shrimp-tang ramen. Guests eat oysters and wine together at the bar table. The raw oysters are large and have almost no fishy taste, and the food is built for a second round rather than a full meal.
