If you want oysters - just go across the street to Caesars' Bacchanal Buffet or any other buffet that serves oysters and eat there. The prices are pretty steep. a dozen oysters after tax/tip is about $30. Might as well go to a buffet and enjoy all the other seafood choices and pay a bit more.
Service was a bit slow as previous people have written. Nothing too horrible - but just noticed a lack of attention as the meal went on and very slow to finish out the payment process.
For 2 people, ordered 2 drinks, a dozen oysters and the seafood boil pot. Came out close to $100 with tip. Totally not worth it... I know everything in vegas is expensive but to enjoy oysters, go else where.
