Evan posted a nice picture of Copacabana. The hour is dusk. The round roof buildings are vendors who sell chilled coconuts. You pay your money, they grab a coconut and a machete. They hack away the top, and stick a straw in it. You can walk along the promenade by the beach watching the most incredible sunsets. Everyone should sip coconut juice and watch a sunset in Rio at least once in their life.
