France's popular chain of frozen-food grocery stores (with some 900 locations in their home country) now has several Tokyo branches, where you can stock up on everything from frozen fruits and vegetables to tasty prepared dishes like gorgonzola gnocchi, asparagus risotto and Hachis Parmentier (aka shepherd's pie.). Frozen tarts, eclairs and other dessert items are big sellers, as are the mini-croissants. This Azabu branch shares their location with a branch of the French grocery Bio C'Bon, which offers a good selection of wines and cheeses.
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.
