An amazing selection of hundreds of craft beers - both domestic and imported - can be found in the refrigerators and shelves of this underground liquor shop, along with a decent selection of sake, wines and liquors. (If you're after whiskey though, Hasegawa's nearby eastern branch is the place to go.)
This is probably one of the two best craft-beer shops in Tokyo, and is much more accessible than its counterpart World Beer Market in Kita-Senju.
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.
