This book is a nice, cute, coffee-table book. It has lovely pictures, text in a font which is difficult to read but looks handwritten, and not much content.
I had hoped to get some significant culinary info for an upcoming trip to Provence, but found this book long on looks and cutesy text but with frustratingly little information. Much better for those trying to figure out how to buy/eat there is "Markets of Provence" and, believe it or not, the Peter Mayle books.
So if you want a nice coffee table book with the name of Mr. Ducasse on the cover, buy it. If you want useful info for planning the culinary part of your trip to Provence (and food in Provence is pretty close to heaven, people), choose another book.
