Europeans may build great cathedrals, but Americans have a genius for bathrooms. At Prague, the WC marries old-world elegance with Yankee utilitarianism. When nature's irrepressible call rises above the club's techno beat, you can drift down to this swank unisex chamber of flickering candles, period furniture and a full-service bar to answer. The style might be described as bathroom baroque. A dripping chandelier throws just enough light to reveal the glinting accessories of nubile fashionistas and their well-groomed mates. The music keeps a respectful distance, allowing one to clear one's mind and bladder in one of 12 stalls set tastefully behind black doors. Roughly the size of a confessional, these immaculate stalls seem designed for a religious experience of one sort or another.
