Daemosan Kalguksu is a neighborhood restaurant near Irwon Station that serves bajirak kalguksu, tteokguk, and dolsot bibimbap. The bajirak kalguksu comes with plenty of purged clams in a clear, cool broth. It opens at 11 a.m. and takes phone orders for takeout before the commute home, with self-service kimchi refills. It sits in the basement of a commercial building, so ventilation is poor.
