Sculptures by the likes of Roy Lichtenstein, Ellsworth Kelly, and Jeff Koons rotate through to remind you where you are sipping that pricey glass of chardonnay. Greatest feature, of course, are the stunning skyline views, with Central Park below. Art-overloaded museum-goers and smart singles order off short list of wines, beer, martinis and bites. Summer only, closes early, enjoy it while you can.
