There has to be a better guide out there . After seeing the five-star review for a previous edition of this book I was eager to buy it for my recent trip to Mexico City. Sadly, it fell far short of my expectations. For starters, the maps are woefully inadequate. There aren't enough of them, they lack sufficient detail, and there is no number and letter grid system. That last problem is inexcusable and made it nearly impossible to find many of the sights mentioned in the book. The overall organization of the book is also not done well and does not seem very logical. Making matters worse, the book is not bound well and actually started to lose pages before my relatively short trip even ended. I have had far better books than this when I have visited other parts of the world. I have to think someone makes a better Mexico City guide too
