Hidden on the balcony level of Grand Central Station, the Campbell was once the private office of railroad magnate John Williams Campbell, a man who clearly had no self-esteem problems. The rooms is as grand as any created by Italy’s Medici family, with a soaring, coffered ceiling, leaded windows; an elaborate fireplace and a Florentine elegance in the fixtures. The only aesthetic dissonance is the modern pop music the new owners have decided to pump in (when this bar was known as the Campbell Apartment the soundtrack was jazz, which seemed more apropos). Make sure you go to the"bar"—there are now three Campbell drinkeries in the terminal, but this is the most evocative.
