Moinhos de Ventos by guilhermebr
Another good tip is to go to the Moinhos de Ventos park for a round and explore the neighbor streets, especially the Padre Chagas street with the coffees and the Moinhos de Ventos shopping center, where you can find bookstores, restaurants and more. On the closer streets there are also sushi bars and other stuff .
