I've heard about it, but… 2- What is Churrasco?

Churrasco is a Portuguese and Spanish term referring to beef or grilled meat more generally, differing across Latin America and Europe, but a prominent feature in the cuisines of Argentina, Brazil, Chile, Guatemala, Nicaragua, Uruguay, and other Latin American countries. The related term churrascaria (or churrasqueria) is mostly understood to be a steakhouse.

A churrascaria is a restaurant serving grilled meat, many offering as much as you can eat: the waiters move around the restaurant with the skewers, slicing meat onto the client's plate. This serving style is called espeto corrido or rodízio, and it's quite popular in southern Brazil.
