Time Out says
Jubako is an upscale eel restaurant which has been in business for well over 200 years. In 1955, it moved from Asakusa to a traditional Japanese-style house in Akasaka. It only offers a set menu – for lunch you'll get a seasonal appetiser, roasted eel liver, koi koku (stewed carp), broiled eel, rice and dessert, while shirayaki (eel cooked without sauce) is added to the dinner menu. You can also order uzaku (eel and vegetables with vinegar sauce) or abalone cooked in salt crust on the side. The restaurant only has private rooms, where guests can enjoy views of the Japanese garden. Because of its location, Jubako is often used for business dinners and can get very pricey. When making reservations, you can ask for either the Japanese room with its horigotatsu (Japanese-style table built into the floor) or a Western-style table. Note that there's a service charge of 15 percent.
