Generally speaking the Eyewitness Guides are second to none, and this guide to New York is no exception. The chapters concentrate on each area of Manhattan and the outlying areas in turn, letting the traveller know all they need to know, where they need to go and how to get there. Each section has it's own mini in depth local map, but there is a larger one at the back which includes subway routes too.
Basically it covers everything in fine detail which means that you can maximise your visit, especially if you are not there for very long, but need to see all the best places.
There is an excellent section at the back which helps the first time traveller to New York find their bearings: - how to travel the subway and bus systems, how to buy metro tickets and how to flag down that cab. Also, there is a guide on tipping and local taxes and even a short history of Manhattan.
As with all Eyewitness guides, it covers restaurants and hotels of various prices and districts, so you can always find a fabulous place to eat, wherever you might find yourself.
The photographs are excellent, and the book has a very clear and easy to understand style to it.
In short, you would be foolish to not pack this guide with you.
