Unagi Aikawa Tokyo is an eel restaurant near Takadanobaba Station in Shinjuku City, Tokyo, serving unagi donburi. Diners choose between Kanto-style and Kansai-style preparation, and skewered eel lets them try different parts of the fish. The eel is grilled after ordering, so food takes about 30 to 40 minutes to arrive, or about 15 minutes after seating if the meal is reserved on the restaurant's website. Even the special grade portion is small.
