401 Restaurant - The "401 Restaurant", which is run by artist He Dongxun (HAHA) and two friends, is a popular barbecue restaurant specializing in Jeju Island pork, located in the area where young people gather. Everyone will be curious why the name of the store is called "401". It turned out that HAHA and like-minded friends lived together during the green period, and the room number at that time was 401. The name of the store was a witness to their deep friendship.
