Buenos Aires runs on coffee and medialunas — buttery, glazed croissant-style pastries smaller and sweeter than their French cousins, eaten for breakfast and afternoon merienda (tea time). The café culture of Buenos Aires is extraordinary: historic confiterías like Café Tortoni (1858), El Federal, and Gran Café Tortoni have been intellectual and social gathering places for over a century. Order a cortado (espresso with a touch of milk), two or three medialunas, and settle in to watch porteño life unfold.
