Do not go here. The Aria hotel is beautiful site and a must spot to visit, but the buffet is the worst I have had  in Las Vegas (I am a local). I went with a small group and ran into friends. The buffet would not let us sit next to each other, or even the same section unless we paid an additional 18% which would have been $60 dollars - just to sit at a table next to our friends (several were open).  The service was really poor from the check-in to the server (who only showed up once the whole time).  To top it off the food was poor even by buffet standard, especially the sushi. Tried to have an open mind but even the prime rib was overcooked and thin, the salad had been siting so long it was soggy. So many better options- do yourself a favor and don't go back..   They are the first restaurant I have ever thought was so bad I would give a negative review.
