Sinui Ju Chapsal Sundae is a sundae-guk restaurant in Cheongdam-dong, Seoul, open 24 hours. It also serves a set meal with extra sundae and meat, eaten with mu saengchae and seokbakji. Dadaegi is set on the table so diners can add it to the broth to taste, and the large dining room means a wait is unlikely. Prices are high for sundae-guk.
