Although the atmosphere at this sake-industry information center is rather utilitarian, they do offer sake tastings during the day, along with occasional special events. Tastings are just Y300, and give you a chance to try a few different types of sake and compare them.
There's also an enormous amount of reading material about sake, although it's almost entirely in Japanese. Videos showing the sake-brewing process are somewhat more accessible. Down in the basement there's an old-fashioned izakaya in case you want to continue your sake research over dinner.
This book will introduce you to more than twenty of Japan's favorite specialty foods that are less well known abroad, along with a guide to the best places in Tokyo to try them and expert tips on what to order. From Bento.com.
