Every ten blocks of the Upper West Side seem to have their own character: the 70s and 80s have their share of “Classic Six” prewar apartments (that’s three bedrooms, a living room, dining room, and kitchen, as opposed to a “Classic Seven,” which has all that plus a room for the maid or domestic staff, sometimes used as a home office.) Along Riverside Drive on the Upper West Side, there are contain some grand-scale apartment buildings with magnificent river views to match the street’s name. Meanwhile, the southern bit of the Upper West Side embraces the Time Warner Center, which has some of the most spectacular luxury condos in the city, along with high-end shops like Coach and Hugo Boss, once-in-a-lifetime eateries like Per Se, and a giant subterranean Whole Foods that seems to hold every resident of the Upper West Side at once.
