Jamsugyojip Yeouido is a naengsam restaurant near The Hyundai Seoul in Yeouido that grills rapid-chilled samgyeopsal (pork belly). It serves 100% domestic pork belly slaughtered the same day, rapid-chilled and presented on an obong tray with paechae, baekkimchi, and garlic stems. Guests walk down a basement staircase and write their name and party size on a whiteboard to wait, and reservations are taken in advance for parties of four or more. The space is open, so the restaurant is loud.
