Nomel is a sake-tasting bar offering sixty different premium sakes for you to sample and compare. They have an open-bar system with no time limit, and since you pour your own sake you can try out tiny sips from lots of different bottles until you find your favorites. The fixed price for the open bar is Y3240, and you can bring your own food, get food delivered, or order oden or grilled fish from the shop's small kitchen.
The decor is fairly minimalist, although unlike some other sake-tasting bars in town at least there are tables and chairs. Online reservations (in Japanese) can be made at their website: sakenomel.jp/system. If they're full on a particular night you might also check out sister shops Sake Lover (also in Kanda) and Bucho featuring Yamachan (near Shinjuku Gyoen), which have the same self-service open-bar system and a similarly wide sake selection.
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.
