Barack Obama and friends surprise Barcelona restaurant

A former president, a world-famous Hollywood director and a rock music icon walk into a restaurant.

It sounds like the setup to a joke, but staff at Amar restaurant in Barcelona witnessed just that on Thursday night.

Employees were left in shock when 44th US president Barack Obama, director Steven Spielberg and musician Bruce Springsteen walked in unannounced.

Chef Rafa Zafra said Amar had been suggested by Spanish-American celebrity restaurateur José Andrés.
