The 23,000-square-foot, 315-genius-staffed mega≠store that Apple just unveiled on the north and east balconies of Grand Central Terminal is, to the surprise of no one, pretty impressive. Nevermind the iPads, the cinematic views of the main concourse alone merit a visit. But it’s not the only new shop worth browsing in the Terminal. Intaglio Antique Prints & Maps (Vanderbilt Hall; 508-414-0530), a freshman vendor at the hub’s holiday market, stocks over 1,000 antique prints and postcards ($20 to $500) as well as nineteenth-century maps from Fairfield County to France. Australian skin-care brand ≠Aesop (Graybar Passage; 212-867-7311) sells primrose- and parsley-seed-packed products from a kiosk made of more than 1,000 stacked copies of the New York Times. The three-month-old toy shop Kidding Around (42nd Street Passage; 212-972-8697) carries mostly low-tech playthings like picture books, block sets, doll houses, and board games. The pantry spinoff of Park Slope gastrobar Beer Table (Graybar Passage; 212-922-0008) is lined with nearly 100 bottles of suds (from $3 to $40). And joining the lineup this week is Eli Zabar Bread and Pastry (Grand Central Market; 866-354-3547), the gourmet grocer’s first free-standing bakery. Grab a prosciutto baguette for sustenance, then plunge back into the iMadness.
