[1] Previous guests have included the composer Edward Elgar, the author Ian Fleming, and various members of the British royal family.

[1] Jack Brooksbank, Princess Eugenie's husband, is reported to have told Richard Eden, the Daily Mail's royalty editor, that there is a secret tunnel from the nearby St James's Palace to Dukes Bar.

[7] The clientele were once described as a typical Mayfair set: "wealthy, tawdry, and slightly disreputable" but fading into the background after a couple of the bar's martinis.

[8] Past guests have included the composer Edward Elgar, who often visited,[9] and the James Bond author Ian Fleming who frequented Dukes Bar where he decided that Bond's favoured drink would be a vodka martini, "shaken, not stirred".

[9][6] The Vesper Martini is the Dukes Bar "signature drink" and includes five shots of gin, with a two-drink limit; any attempt to purchase a third one will be declined.
