After a thorough refurbishment in the late 1990s, this classic Beaux Arts building – a bustling train hub that relentlessly shuffles commuters in and out of the tri-state area – serves as home to several great restaurants (Michael Jordon’s The Steak House, Cipriani Dolci, and Metrazur, the peerless Oyster Bar), a high-end market, specialty shops, and the exquisite, clubby bar the Campbell Apartment. The common areas often host themed exhibits and cultural fairs, and the Tiffany blue-domed ceiling illustrates the constellations.
