Buenos Aires
In Buenos Aires, you can always spot the out-of-towners. They’re usually wandering around the streets in the evening, hungry for dinner at 7 p.m.—and wondering why none of the restaurants have even turned their lights on yet. As a rule, the locals have a light breakfast (often coffee and medialunas—sweet, croissant-like pastries), a late lunch, and merienda (a snack with coffee, mate, or tea) around 5 or 6 p.m. Dinner never happens earlier than 8:30 or 9 p.m., often much later on weekends. Note that the city empties out in January, with many porteños away on their summer vacations.
