Yongga Hoejeon Hwogwo Gangnam is a Chinese all-you-can-eat hot pot restaurant in Seocho-gu, Seoul, a short walk from Gangnam Station and behind the Musinsa Store at Sinnonhyeon Station. Diners choose hongtang, baektang, or tomato broth and pick meat, vegetables, and Chinese ingredients from a rotating conveyor. Broth and extra ingredients are ordered by QR code, and a train brings the food to the table, with a 90-minute limit. The waiting area is small, and the conveyor slows when the restaurant is crowded.
