Buyeong Dogani-tang is a 30-year-old Korean restaurant at the entrance of Samcheong Park in Samcheong-dong, Seoul, serving dogani-tang, gomtang, and dogani-suyuk. The clear broth is made from Korean Hanwoo dogani and sagol. Meals are available early in the morning, and food arrives in under five minutes after ordering. The dining room has only four to five tables, so arriving late means waiting.
