Seongsan Susan Sikdang 성산수산식당

Two slices of mackerel at a time get a deep dunk in the house sauce before being wrapped in a leaf, and the owners talk first-timers through it. The glossy fish has no fishy edge, and the jiri-tang, a clear fish soup served alongside, is rich. A married couple runs the small shop, and mackerel sashimi can be packed to go even as a single portion.
