Foolish gaucho-guys aside, the meats were excellent, particularly the pork tenderloin. When we got home, we did a web search and found that the marinade used was simple - lime juice, salt and garlic. We tried to duplicate it and it came out right the first time. Kept the meat tender and juicy and way flavorful. Good stuff, even without the swords and gauchos!

We have several of those in northern Virginia and central Maryland. Most of the gauchos barely habla Ingles. Not sure if they're Brazilian, Mexican, or what, but it does lend a certain air of authenticity. And the meat (pork, lamb, chicken, turkey, sausage, and several cuts of beef) is excellent. All you care to eat; it's Atkins Diet heaven. Not that I'd doing AD; some friends are...
One of the absolute coolest restaurants I have ever been in was called Carnivore.
Located in Johannesburg, South Africa, they cook various wild game on Masai swords.
All of the game is raised on a reserve. Some of the meats include wildebeest, impala, ostrich, and gazelle.
Here's a story about the one in Kenya, which has the same menu as the one in Jo'burg.
