Rio splits by zona: Zona Sul is Ipanema-Leblon money, Zona Norte is Maracana working-class, Centro is business ghost town by 7pm. The Ipanema Posto number tells your tribe: Posto 9 is where creatives and LGBT gather, Posto 8 is families, Arpoador between beaches is where locals watch sunset and applaud. Skip Copacabana kioskos tourist prices; go to Bar Urca for cerveja at seawall sunset. Never wear Sao Paulo team jerseys, and speaking Portuguese with a Spanish accent gets you priced up.
