This buffet used to be great. Now it's terrible. They raved about the seafood (costs $30 extra), but I didn't see any value in it at all as the regular buffet had shrimp and crab as well.
Didn't care for any of the food. Very very low grade stuff. There was hardly anyone in the place on a Friday night and I should have known better.
The hotel used to be so much fun too. They had a Mardi Gras float and entertainment, but that's gone now. Only thing left is a smoky casino. I don't know what happened, but I'll never go back to the Rio again. It's awful.
I recommend you avoid this place and try the Wynn buffet or the Bellagio, or even the Paris one.
