Prospect Park is a great place to have a water balloon fight, a picnic, a jog, and play with other people's dogs.

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.

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.

Best lobster roll outside of Maine. The brunch is a well kept secret. Chicken and waffles and shrimp & grits are my picks for brunch.
