Yes, this all-you-can-eat buffet has a larger sushi section, but it's still buffet quality sushi. Rubbery and cold with hardened up rice.
Other than the sushi, it's typical asian buffet fare. Chicken wings (greasy and overloaded with lemon), beef and broccoli (salty), egg rolls, lo mein, etc.
If you are really craving sushi I suggest going to a regular AYCE sushi place. Which is not to say there is anything wrong with buffets, but that the sushi here isn't anything special.
