"Barbecue Nation," a new exhibit at the Atlanta History Center, takes a deep dive into the history and culture of the South's most-loved food. But barbecue, like the South and the rest of the United States, is increasingly global. So "On Second Thought" is setting out on a series of roadtrips to see how different cultures and countries represented right here in Georgia do barbecue.

We started off with a visit to Chama Gaúcha, a Brazilian restaurant in the Buckhead neighborhood of Atlanta. Nelcir Muller, the general manager, took us inside the kitchen to show us how people in Brazil — South America's largest country — make their barbecue. In Portugeuse it's called "churrasco."
