While they may be a tad more expensive than the average Tokyo craft-beer bar, this small chain (with branches in Shinjuku, Akihabara and Tokyo Skytree) does its own importing, and carries some interesting beers that you won't find elsewhere in town. They also serve a fuil food menu, not just bar snacks. Open all day on weekends.
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.
