The Grand Central Partnership (a business-improvement district) has installed a number of information booths in and around Grand Central Terminal (there's one near Vanderbilt Avenue and East 43rd Street). They're loaded with maps and helpful brochures on attractions throughout the city and staffed by friendly, knowledgeable, multilingual New Yorkers.
NYC & Company runs Official NYC Information Centers at Macy's as well as in Lower Manhattan at City Hall Park, South Street Seaport, and in Chinatown, at the triangle where Canal, Walker, and Baxter streets meet. Its official visitor guide and map, both downloadable from NYC & Company's website as well as in hard copies available around town, are both very useful.
The Downtown Alliance has information on the area encompassing City Hall south to Battery Park, and from the East River to West Street. For a free booklet listing New York City attractions and tour packages, contact the New York State Division of Tourism.
