We ate there last night. We eat here about 3 times per year. The sushi with sauces tends to be ok. They don't have a very big variety on their AYCE menu. There are a lot of rolls on the menu, but if you look close most of them are very similar. The sushi and nigiri without sauces tend to very very very dry. The service is usually good, but if there is someone at the sushi bar that speaks Japanese, you will be ignored. We were the only other customer other than the Japanese speaking customer last night. The chef, the owner, and the waitress spent all their time talking to the Japanese speaking customer. We waited much longer than normal to get our food. If you are going to get AYCE, it's the best place I have found in Summerlin. If anyone has found a better place, please let me know.
Do not order take out. Even though they know me there, the take out is horrible. If a roll comes with sauce, they will not put the sauce on the roll. They are very hesitant to give you containers of sauce for the rolls that you pay for.
