Query: Frustrating! Incomplete index

Using this book can be very frustrating. Rather than being organized alphabetically, the book is organized by region, which has its advantages and disadvantages. But with the guide's incomplete index, this is extremely frustrating. For instance, if you want to read up on Annecy, Lac du Bourget or Chambery, all of which rate multiple Michelin stars, you will not find them in the index. So after looking in the index and not finding them, you have to go find the table of contents. What is the name of the region? A for Alps? No such category. So you scan the table of contents trying to find the appropriate category - ah, there it is - FRENCH Alps! And yes, there you can find Annecy and the page number.All in all, an experience that is bound to raise your blood-pressure. Avoid this book!
