As a beginner in making sushi, I found the book invaluable. The extra sections on how to order and conduct oneself in a sushi bar were an unexpected bonus. The only reason I did not give this book five stars is that the URLs for online resources for equipment, spices, etc. were either no longer working or the site was not that well stocked. In one case, my security software blocked entry to a site on the grounds that it was dangerous. (Naturally, I didn't go there.) Otherwise, I just loved the book.
