I don't do buffet restaurants because I find the concept of other people digging in the food I am going to eat a bit gross. However, Leo the sushi chef does a great job and the sushi is always fresh. Recently I got a rainbow roll and some salmon sashimi and it was very good and artfully prepared. My wife said the california roll was good also. Her only complaint is that the rolls are cut a little thick making it difficult to eat each piece in one bite.
They also offer delivery if they have enough staff when you call.
