Time Out says
Kyo Aji is known as one of the best kaiseki restaurants in Tokyo, and the owner, Kenichiro Nishi, has even had his name appear in the gourmet-focused 'Oishinbo' manga series. The restaurant offers delicate dishes using unique Japanese ingredients such as hamo (conger), konowata (salted sea cucumber intestines), zuiki and soft roe of sea bream. A popular way to finish off a meal is with harasu gohan (rice with fish belly). Reservations fill up as far as one or two months ahead, but if you're lucky enough to get one for a counter seat, you might get a chance to have a nice chat with Nishi himself.
