For nearly a quarter of a century, El Pirata has been serving tapas to customers including local office workers, South American oilmen, Japanese diplomats, Mayfair hedge fund managers – and the occasional celebrity, like Queen guitarist Brian May and that most famous of modern pirates, film star Johnny Depp. The secret to El Pirata’s long success is simple: a vast choice of good Spanish food and wine served quickly by friendly waiters in an informal restaurant that feels more Madrid than Mayfair.
