Here are three canny covert concoctions to leave you shaken and stirred, available now at London's most top-secret cocktail bar.
This dossier of daring drinks is now being served at the Raffles London at the Owo Spy Bar, hidden in the depths of the Old War Office building in Whitehall.
Here, one of the old GHQ interrogation rooms now plays host a sumptuous cocktail bar serving captivating drinks for secret agents and their cunning accomplices alike.
Turn the clock back to an era of wartime espionage with a Dig For Victory Martini, combining our awfully english vodka with English dry vermouth, rhubarb and cherry and a limited edition Eau de Vie.
Or decode the enigma of two other tantalising twists on the classic vodka martini, one laced with salty olives and ripe apricot and the other made with bitter walnut and tangy English apple.
And you needn't be on His Majesty's secret service to gain access to this undercover space, simply search for the door marked 007 and knock.
