Buenos Aires moves between Belle Époque palaces and graffiti-lined Palermo streets, where century-old cafés sit blocks from natural wine bars and tasting-menu parrillas. Tango spills out of San Telmo's cobblestones as Recoleta's marble mausoleums give way to Puerto Madero's glass towers, a city as European as it is unmistakably porteño. It runs on mate — an unhurried ritual of shared yerba that turns any afternoon into something communal.
