@MrItty , you’re thinking FAO Schwartz.
@LKidKyle, a few other things from a New Yorker:
The Museum of Natural History is right next to the Planetarium. Go early and see both on the same day.
Depending upon WHEN you come, the Yankees and the Mets have brand new stadiums you might want to check out. (The Yankees in the Bronx; the Mets in Queens).
Look up the following Restaurants: Mars 2112, Russian Tea Room, Tavern on the Green, Jeckyl and Hyde.
also Chinatown and Little Italy are right around the corner from each other. Again, a same day thing. Then go to the South Street Seaport.
Do take a look at Ground Zero, where the World Trade Centers used to be.
If you are near Rockefeller Center around 7 am, be part of the “Today Show” crowd and wave to your friends from television. Also take the tour of NBC.
