The word is "rodizio." Literally, one eats meat until one signifies defeat, or bursts, whichever happens first.
They come to your table, knife in one hand, all manner of juicy, skewered grilled beast in the other, daring you to let them slice it and drop it onto your plate, already bulging with potato salad, beans, piri-piri, and whatever you foolishly took from the buffet.
You eat, and eat, and eat, and then they tell you about the incredible desserts. Above, the meat on the plate is sirloin, sliced right at the table, and pork sausages called "chouri?o." Below, from the buffet, beans, potato salad, green salad, farofa, beef with peppers, and piri-piri. Afterwards, I had flan.
Seriously, Brazilian steakhouses are not to be believed.
