When I lived in Rio de Janeiro, there was a relatively recently developed area that looked nothing like the rest of the city. Unlike most of Rio, Barra da Tijuca, located along the southwestern coast of Rio, had many huge private mansions often painted in pastel colors and palm trees within heavily-fenced yards, and high-rises that resembled South Beach much more than Botafogo or Central. These buildings made Barra look much more like Miami than Rio de Janeiro. It was so obvious that many Brazilians I met even called it “o Miami do Rio” (“the Miami of Rio”).
Apparently, though, things have changed somewhat, and now Miami is the Miami of Rio.
