It's sugar-coated shabbyness. I have been there in wintertime, all the rides and attractions were closed, but it´s still nice to have a walk on the beach or spot some funny looking storefronts and vintage-looking rollercosters. A perfect backdrop for photoshootings, a gem for friends of vintage typography. On 4th of july hot dog eating contests are held here (they actually do that!).
Its an image imprinted in everybody's mind: the background for hundreds of movies, ads and commercials. Actually standing on a saturday-night at Time Square, hearing dozens of different languages of tourists around you, and being fully emerged with the sounds and light, slightly frantic and crazy… You are in NY.
Apart from Dia Beacon, in Beacon (upstate New York about an hour away from Grand Central Station) and also the Judd Foundation in Soho, this institution is absolutely one of my favourite places to visit and it is located in Long Island City, Queens. It showcases sculpture in the broadest sense and has an incredible building that used to be a workshop that refurbished and fixed subway cars. It has been running since 1928 and when you visit you will definitely see why that is.
