Food was mediocre at best. I had the prime rib (16oz) and my wife had the cheeseburger. I managed to gnaw through my meal, but my wife chose not to finish her burger. While the food was barely eatable, the service made the whole experience unbearable. We were at the Rio for the Penn & Teller show, so when the waiter did not appear at our table at first, we called over the hostess and told her that we where in a bit of a hurry due to the show starting soon, to her credit she walked over to a server and told him...he, I assume louder than he thought, said something to the effect of \"seriously? the show doesn't start for an hour, they should calm down\"...rude! Now flash forward 50 mins to me standing near the server station trying to get someone to cash me out so that we could run to our show.
