Decent Introduction to Bento,
This review is from: Hello, Bento!†- A Collection of Simple Japanese Bento Recipes (Kindle Edition)
This book provides a decent introduction to Bento and provides recipes for several Bento staples as well as some decoration tips.
The focus is clearly on the recipes. Those who are interested in the decorative side of bento would probably better served elsewhere. One of the US reviews also misses food safety information. That reviewer certainly has a point, since there are no hints about food safety. However, exercising normal caution should help here.
