Part cocktail lounge, part historical reenactment, Bart's is "London's worst kept secret" and runs like a 1920s speakeasy. With a website that doesn't give you an actual address (don't worry we found it) and only provides clues to its whereabouts, it seems almost impossible to find?making it all the more exclusive. Bartenders dress in '20s fashions and serve libations in tea cups, hats and even gramophones?just in case the coppers show up.
