Ssangdungi Susan Main Branch 쌍둥이수산 본점

Sekkosi, small fish sliced with their fine bones left in, has a crunchier bite than fillet-only sashimi. The shop also prepares gwangeo makhoe, roughly cut flatfish, so when ordering it helps to say both which fish and whether you want it bone-in. The main branch is at 195 Bomun-ro in Seongbuk-gu, toward the Sungshin Women's University station area.
