Tomo Ei.

Restaurant Tomo Ei, also known as Unagitei Tomoei, is a Michelin-starred culinary gem in Kanagawa Prefecture, celebrated for its premium _ao-unagi_ (blue eel). With less than 10% of market eels being this rare variety, the restaurant excels in offering an extraordinary dining experience. Eels are meticulously raised in spring water sourced 100 meters underground, enhancing their flavor and quality. Freshly prepared upon ordering, the grilled eel is served over rice with a sweet sauce, complemented by seasonal sides like _kimosui_ (eel liver soup) and local _kamaboko_ (fish cake). Tomo Ei’s intimate setting includes private dining rooms and tatami mats, making it an ideal spot for savoring exquisite dishes and unwinding. Reservations are highly recommended due to its popularity and often long wait times, which only amplify the anticipation for a truly unforgettable meal.
