Rio de Brazil Steakhouse is a version of a chain of a Brazilian style of steakhouse that’s become popular in the U.S. called Fogo de Chao. Here is what wiki has to say about Fogo:
Lunch and dinner at Fogo de Chão operate the same and consist of the same items, at different prices. There is a fixed price for endless salad bar and tableside meat service. Customers can choose just their favorites, or simply wait for their favorite cut of meat to make its rounds.
The meal comes in two parts. The first starts at the gourmet salad bar, which offers cured meats, smoked salmon, imported cheeses aged from 1-30 years, vegetables, and salads. The second part of the meal consists of fifteen different cuts of beef, pork, chicken and lamb, served tableside.
Same idea, as I understand it, with Rio de Brazil Steakhouse. More as I get it.
