Four of us had dinner at Buzios. My friends split a pound of crab legs which they said were excellent. My wife had poke which was also very good. I had the linguini Fra Diavolo. It was bland, tepid and entirely forgettable. Service was pretty good, except they brought us white wine that wasn't chilled. Overall my impression is that you can eat pretty well here if you keep your order simple. This isn't fine dining and its expensive for what you get, but if you're staying at the Rio and don't feel like venturing out, its a good safe harbor.
