Kai Yeouido serves Jeju saengdeungsim tangsuyuk and hwangje jjamppong on the first floor of a building in Yeongdeungpo-gu, Seoul. The Jeju saengdeungsim tangsuyuk comes with fried broccoli and mushrooms, and the hwangje jjamppong is large enough that two men can eat it and still have some left. The restaurant has several rooms and hall seating, and the hall is furnished with chairs and sofas. It is a clean Chinese restaurant, but it does not have a distinct character.
