The Frank Stella’s are the best. They are all over the city and they always look amazing. Two of my favorites are the Saatchi and Saatchi lobby (pictured) and the Citi Corp building in Midtown.
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.
Beach approachable by public transportation and can be connected with a visit of MOMA PS1 Art Installation (Katharina Grosse House) Also less crowed than other beaches in NYC.
