Came here for the second time recently, and it was even better than the first. I was a little worried because I noticed a bunch of recent reviews complaining about the service, but we had no issues for our party of six.
Gauchos and servers (exclusively men and exclusively women, respectively - sexist?), were all very attentive and helped direct more of our favourites along to our table. We were seated near the buffet, which we were a little concerned about, but it just helped to ensure we were never forgotten (maybe that's the secret if it's really busy?).
Anyway, if you want yummy all-you-can-eat grilled meat, come here.
