Venture up a quiet side street off the heaving Copacabana beach in Rio de Janeiro and brave the narrow, cobbled inclines to the Chapéu Mangueira slum, and you'll find one of the city's best restaurants, Bar Do David. Outside, a few plastic chairs bask in the sun; inside, the back wall has been transformed into an intricate re-creation of Rio's favelas, or slums.
