A nice little cafe on land side of Terminal 1, next to the checkin area. It has some decent coffee and more variety than in other coffee places nearby, not to mention the typical Brazilian desserts. Speaking English could present a few problems, despite it being an international airport. Fortunately they deviate from the traditional "cafezinho" and "café com leite" with more options - latte, capuccino, americano, etc - making it worth stopping by if you need a bit of caffeine. But do expect to pay airport prices.
Another noteworthy info is that they have recharging stations (albeit with the tradition 3-pin Brazilian plug) but no wifi - although you can use the airports free wifi. read more
