Seongsu

A 1970s building left largely as it was — it served as a supermarket, diner, home, garage and workshop before the bakery took it over. Two minutes from Seongsu station, exit 2.

A 1970s rice mill that became a warehouse in the 1990s — the building people picture when they say “Seongsu warehouse cafe”. What hangs on the walls changes from time to time.

The anti-Instagram counterweight to Seongsu — and the best meal on this list.

A stationery shop staged like a film set. Dangerous for your luggage weight.

A village of tiny brand rooms stacked inside an old car-repair factory. Start on the top floor and drift down.

The market has stood in its current form since 1962 and has 139 units. Long-running shops sit beside ones opened by young merchants through a 2016–18 youth-merchant program, and as Seongsu’s commercial scene has grown, some units have shuttered and now stand empty.
