I read that the design of Central Park's curving spaces was a Romantic counter to the geometry of Enlightenment-era gardens. I heard this design was influenced by landscape painting, where its foreground, middleground, and background constantly shift as you walk the paths. I find new pockets and features every time I'm there. One of my favorite spots is with the Central Park Dance Skaters, a group that roller skates in circles all day to vintage electro funk. These characters generously lend you the feeling of being in your own 1980's New York film.
The oldest still-operating restaurant in New York City, still in the family of the original founders. At Christmastime, it's decorated to the nines. Go with a big group: portions are large and the wine flows liberally. Look for the little buttons on the walls: in the old days, the mafia would hang out in the back room, and if diners saw the cops come in, they'd press the buttons so the mafia guys could run out the back.
