I have to say this was the biggest disappointment ever, I have traveled all over eating at sushi places and quite frankly this has to be the worst sushi I have ever had. They raved about Chef Masa,and how fresh the fish was ...sorry chef but the yellowtail risotto was bland,the yellowtail was skimpy and not cut right ,oh and chewy .(never had chewy yellowtail,but ok) the lobster tempura roll was an abysmal. There is a reason that at 8:30 on a Saturday night in Vegas,there isn't more than 20 parties in this huge restuarant ? And god forbid you say something and Michael the server treats you like a leper. WOW,is all I can say for a restaurant in Aria ....WOW !!!!
