 During the 2008 APEC Economic Leaders ' Meeting , Peru promoted its pisco sour with widespread acceptance . The cocktail was reportedly the preferred drink of the attendees , mostly leaders , businessmen , and delegates . American celebrity chef Anthony Bourdain also drew attention to the cocktail when , in an episode of his Travel Channel program No Reservations , he drank a pisco sour in Valparaíso , Chile , and said " that 's good , but ... next time , I 'll have a beer . " The broadcaster Radio Programas del Perú reported that Jorge López Sotomayor , the episode 's Chilean producer and Bourdain 's travel partner in Chile , said Bourdain found the pisco sour he drank in Valparaíso as boring and worthless ( in Spanish : " A mí me dijo que el pisco sour lo encontró aburrido y que no valía la pena . " ) . Lopez added that Bourdain had recently arrived from Peru , where he drank several pisco sours which he thought tasted better than the Chilean version .
