Food specialties of Yamagata Prefecture are sold here, including giant bags of rice, some odd-looking eggplants, and crunchy rusk in flavors like blueberry, chocolate and garlic. There's a fair amount of sake, but less than we expected; they also offer a good selection of wines. Up on the second floor is a restaurant serving regional cuisine (03-5250-1755).
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.
