I have never been to an actual Benihana restaurant (except maybe when I was very young) but as a child my family would occasionally go to a local, family-owned (I think?) teppanyaki or hibachi-styled restaurant. My parents really never cared for it (more expensive, took longer) but of course I loved the spectacle and the show, etc. So I was super excited to see this book.
This is the story of founder Rocky Aoki and his life. How he Aoki who did not attend a Summer Olympics as a wrestler but would go on to found this restaurant chain in New York City, from its formation, the concept behind it, how it expanded, etc. Much of the book is dedicated to Aoki's life, from his childhood to Japan to moving to the US to his marriages and family, etc.
Overall this was mildly interesting but is probably only for the most hardcore fans who are interested in Aoki himself. I wanted more about Benihana or even about the business aspects of the restaurant (even though business management-type books aren't really my thing) and was not particularly interested in his life outside of the restaurant.
Ultimately this is a skippable book if you're specifically interested in the history and background of Benihana or hibachi restaurants or its business strategy, etc. You have an interest in Aoki himself this might be interesting to read but I would not rush out to find a copy.
I was lucky that my library had a copy, and I would ultimately recommend it as a library borrow. I wouldn't be surprised to see this in the bargain bin either, which would be a good option if this isn't a title your local library system plans to purchase for its own collection.
