Nihombashi Iseisada Daimaru Tokyo Branch is an eel restaurant on the 12th floor of Daimaru Tokyo, connected directly to Tokyo Station. It serves Kanto-style unagi don, steaming the eel once before grilling it and pairing it with a tare that is low in sweetness. Window seats look down over the Tokyo Station platforms and the Marunouchi office buildings. The rice is overly soft and sticky.
