Yongseol Wang Jokbal is a jokbal restaurant in the Oryun Building in Yeouido, Seoul. It boils the pork trotters twice to serve them tender, and at lunch it also offers a set of kalguksu and jokbal. In the evening the jokbal sells out early, so takeout requires a reservation in advance. The interior is small with small tables, so when there are no seats you have to wait outside.
