Parents came to town last weekend and took them to Kappa after reading some ancient postings on this board. Were not sure exactly what to expect - which was part of the adventure - but it was a unique and wonderful experience. It could tritely be called a more formal and refined Japanese version of Jai yun, but that would be unfair to both places. All that is really similar is the procession of many small courses and the creativity that separates those courses from anything I had eaten before. Like Jai Yun it is not cheap ($75 a head) but I consider Kappa to be a bargain.
Highlights included two fresh imports from Kyoto - a tiny rock squid, eaten whole, and a sweet white turnip, which was sensational. Also the monkfish liver with spicy radish and vinegar, uni in a couple of guises, and an extraordinary array of different vegetables and seafood. No meat other than some exquisite duck breast.
we had a table for four in a separate room and flawless service. three bottles of sake that varied widely and were all reasonably priced. really a special gem.
