• The Winter Dance Celebrates “Gold.” American Museum of Natural History, Central Park W., nr. 79th St., 7:30 p.m. Hundreds of young rich people — including our pals Tinsley Mortimer and Fabiola Beracasa — will dine in the Grand Gallery and then have dessert and dance under the blue whale in the Milstein Hall of Ocean Life. It’s socialite prom!
• Milk Salon opening. 450 W. 15th St., nr. Ninth Ave., 8 p.m. Chef David Bouley will prepare a tasting menu for fashion folk like Zac Posen, Francisco Costa, Jessica Stam, Alice Temperley, and others. It’s actually a post–Fashion Week eating competition. Jessica’s Stam’s competitive-eating-scene name is “Feral Cat.”
