I've now unintentionally read consecutive books where the author has recently passed away. Writers beware if your book is about to be profiled on this site! Anthony Bourdain was a celebrity chef and author who hanged himself last month at age 61. In Kitchen Confidential Updated Edition: Adventures in the Culinary Underbelly he shares suggestions for life and business based on his experiences as a top chef.
It's kind of aimed at everyone. There are culinary tips for those who barely cook all the way to professionals. There's business advice specific to the restaurant industry, but that apply generally. And there is life advice, mostly in the form of avoiding some of the things he could not (e.g. don't become an addict!)
I found the beginning pretty slow and boring but it got a lot better fast. The writing style is entertaining and humourous.
I had no interest in owning/running a restaurant before reading this book, and I have even less interest in it now. Seems like a tough business! If you don't have a passion for the food and its prep, the administration stuff will probably kill you.
