It's easy to walk past this basement restaurant located on an East Village side street without noticing that "one of the most authentic, Kyoto-style kaiseki experiences in the country" happens to be inside. But venture down the stairs and they might offer you thin slices of yuba stuffed with sea urchin or a bowl of Japanese white turnip potage with tsukune-style minced chicken and Kamo Shio-yaki - slowly grilled magret of duck with Mongolian salt. And if you're lucky, you can celebrate the start of the hamachi season with a few slices taken from a hunk of fish that cost $2,000, which was delivered from the fish market in Tokyo earlier that day. They allow BYO, if you don't wish to choose from their list of rare sakes.
