Marusim Gangnam serves eel over rice at its location in Gangnam, Seoul. Its main dishes are hitsumabushi and unaju, and the hitsumabushi can also be eaten with ochazuke. The hitsumabushi is grilled to a charred finish and the unaju is ordered soft, with the accompaniments differing by menu item. The restaurant has a break time starting at 3 p.m., so a meal is not possible at 2:20 p.m. either.
