Hamru Yeouido is a Japanese restaurant on the third floor of the Yuanta Securities building in Yeouido, Seoul. It serves hitsumabushi, a grilled eel rice dish, with eel that is soft and free of fishiness, rice soaked in seasoning, and side dishes served alongside. Reservations by phone secure a room, and room booking requires a party of four or more. Staff explain how to eat hitsumabushi, and because the rooms have no call bell, guests step outside and wave to request more side dishes.
