Mostly a standing bar with just a few stools, BarBar is a pleasant enough spot in which to grab a quick snack and a craft beer or two on your way to the train. There are a few Japanese microbrews on tap (from Y520 for a small glass) and several more by the bottle (Y930/Y1030), although the selection is smaller than average. The food is billed as "homemade deli" - grilled octopus, yakisoba, hot dogs, prosciutto - with most items priced at Y500.
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.
