Yonggeumok is an old chueotang restaurant in Seoul that serves both Seoul-style and Namdo-style chueotang. The Seoul-style version is spicy and resembles yukgaejang, while the Namdo-style version uses ground loach and is not spicy. It opened in 1932 and has continued for over 80 years. The Seoul-style chueotang has a weak loach flavor.
