Osori Sundae is an old sundae restaurant near Yeonsan Rotary by Yeonsan Station in Busan, serving sundae, sundae guk, and suyuk. Its sundae guk is made Seoul-style with a generous amount of perilla seed powder, and the sulguk comes with sundae and offal and is eaten with chive muchim. In the evening it is crowded enough that there are no seats, and when the main building fills up, guests are directed to an inner annex that is quieter but cold. The inside of the restaurant is not clean.
