I discovered these in the 90's when I spent a week in Rio. Also known as churrascarias. For a week I ate churrascaria for lunch and dinner. You go in and pay 1 price for the meal. They have salad bars and other stuff you can go up and scoop onto your plate but the real attraction is the meat. "Gauchos" wander around with skewers of meat and slice it off onto your plate until you say when. All kinds of different meat, sirloin, tenderloin, filet mignon, sausage, poultry, pork. And you keep eating until meat is oozing out of your pores. These places can be found all over the country now so there's probably one near you. I recommend you try the guarana soda. It's the national soft drink of Brazil like Cola is for us. If you want something stronger, try the Caipirinha, the Brazilian mojito, made from Cachaça, a spirit made from sugarcane juice.
