Porcao is a chain restaurant in Brazil, and there’s one in Brasilia as well, near Pier 21. It has a huge picture of a pig on the sign, and you’ll find out why once you go inside. At Porcao, you can eat as much as you want. You have a sign on your table with a stop sign on one side, and a green “go” sign on the other.
Once you turn the sign to go, waiters will come around with plates of food (mostly meat, although there is salad and sushi as well) about as quickly as you can eat it. They won’t stop until you turn it to “stop.” At Porcao, the beef and pork are especially delicious. You’ll be sure to get enough to eat there!
