Jinsim Wangdonkkaseu Cheonan Seongseongjeom is a donkkaseu restaurant in Seongseong-dong, Cheonan. It serves cheese waterfall donkkaseu with naengjjolmyeon, and lettuce wraps with ssamjang and oi gochu. A self-service bar holds children's tableware, small plates, and scissors, and orders are placed on a tablet. The wang donkkaseu portion is large enough that finishing one alone can be a burden.
