Sandra Gustafson's book is absolutely essential if you are not interested in paying overpriced tourist food when you visit Rome, Florence and/or Venice. Like the title, this book covers restaurants in Florence, Rome and Venice. In each city, restaurants are further divided into several city zones. There are maps to each city zone with numbers corresonding restaurants indicated on the map. They are not the most detailed map but good starting point, nevertheless. I have noticed a few mistakes on the map such as the numbers are placed on the wrong side of the street or mistakenly placed on the next street over. It is best to cross reference this book's map either with your hotel or with a different map.
There is a quick reference section next to each restaurant that display vital information: credit card, reservation, cover charge, hours and etc. She also writes a short and personal comments for each restaurant, indicating the history, owner and sometimes what to order. One important note,
I think the real strength of this book is in Rome. It almost never failed me. I had experienced with this book that would have been impossible to find unless you are a native to the city or know someone there. Most of the restaurants have English speaking staff, especially when in Rome. There are a few ( these tend to be the best!) places that doesn't so have your Italian Phrase book handy!
