certainly not in copacabana or ipanema
There's the rub... the thing is that coffee is thought of more of a get up and go, working day-type ritual, and not as much of a "go to the beach and relax" type thing. These are tourist areas inhabited by a lot of foreigners, Brazilians with second homes, and people who work elsewhere. That said, there are still plenty of great coffeeshops and in those neighborhoods: http://www.armazemdocafe.com.br/secoes/page/8/Nossas-Lojas
It's also worth pointing out that a lot of people drink their coffee at places that might look like outdoor bars as most of them also serve it (though generally not the gourmet stuff).
its been too hot to really drink coffee anyway.
Never! :D Anyway, it's actually gotten a bit nippy lately with a few chilly, rainy days. Of course, as soon as is dips below 20° C, the locals all start saying "Ai meu Deus!" and claiming they're about to freeze to death! Perfect coffee weather in any case...
