Donghae Haemultang is a neighborhood restaurant on the second floor near the Sangdo-dong mineral spring in Seoul, serving haemultang, altang, and donkatsu. The haemultang and altang use a spicy, clean broth and come with dolsotbap. A husband and wife have run it in the same spot for a long time, and the donkatsu is made in-house. The interior is not particularly clean.
