Sangoll is a sundae restaurant inside the Bongcheon Jungang Market arcade in Gwanak-gu, Seoul, selling sundae gukbap and modum sundae with offal. Ordering the modum brings two plates: one with head meat and suyuk, one with sundae and its parts. Around 7 p.m. on a weekday there was already a wait, and leftover food is packed for takeout. The interior is small and on the noisy side.
