They serve food as if it was a gift they're giving to you. It's very good vibrations to stay there, one of my favorite places ever.
Jacarandá is in an old house near Parque da Redenção and the service is made by a group of people that really loves what they do. So, food tastes different. They also serve fish but for vegans it is not a problem cause it's a plus to the single dish.
May sound a little expensive because of the size of the dishes, but it's deceptive.
