It time to look for another seafood buffet, off-strip and a non-casino restaurant. It is not that Rio Seafood Buffet is bad, nor it is good. I think for me, it lies in between mediocre. Crab legs are thinner than most buffets. Oyster is borderline frozen and very few and far between are 'pickable'. Salmon sashimi is cut in itty bitty portions though it still tastes great. Their sushi selection and taste were average. What I did like is their gelato selections for dessert. They were delicious and quite tastey.
Rio Seafood Buffet is more like a 3 stars. However, there is just a lot of good seafood buffets back in my area at almost half the price. Rio's high entry price really dragged it down to 2 stars.
