Sangolgokcha Naengmyeon is near Hyochang Park in Yongsan-gu, Seoul, and serves green tea bibim naengmyeon and large donkatsu. The green naengmyeon comes with dadegi mixed in, and the old-style donkatsu is served with soup. The donkatsu is large, and saengseon gasseu and kalguksu can also be ordered. The taste has recently declined from what it once was.
