Neighborhood: Brooklyn Heights, Brooklyn
Address: 130 Livingston St.

Don't let the museums in Manhattan monopolize all your time. The Transit Museum in Brooklyn is a must for tourists and natives alike. The subway and its precursors have a fascinating history, full of death and intrigue (like any big organization that serves the public should). You can explore subway cars of past eras, complete with era-appropriate advertisements, easily the highlight of the trip.
