A book that is an amazing source of info for the ins & outs of every neighborhood is the NFT (Not For Tourist) guide of New York City. You can buy this in any Barns & Noble and make sure it is the most up to date version because there is a new version every year. Another great way of getting to know a neighborhood is by Googling it. With an endless source of information in cyber space why not take advantage of it. If you prefer doing it the old fashion way, taking a stroll through the neighborhood, go for it! But make sure you have your trusty NFT guide with you so you can spot the important things.
