100-Year Seolleongtang Daehakro is a Korean restaurant in the alley across from Marronnier Park in Daehakro, Seoul, serving seolleongtang, doganitang, manduguk, and yukgaejang. The seolleongtang uses a milky broth boiled for 24 hours with meat, served with kimchi, kkakdugi, and buchu. It is open 24 hours, so meals are possible late at night, and the broth is on the thin side. The taste has changed from before.
