Open since 1924 and known as the "Bower of Love," this is one of London's most glamour-puss settings. Once a haunt of royals and consorts, the boîte brought in such stars as Noel Coward, Marlene Dietrich, Fred Astaire, and Frank Sinatra. These days, it pays host to the A-list -- Kate Moss, Puff Daddy, and Madonna. Tube: Piccadilly Circus.
