Average quality buffet sushi. Note that this is in comparison to buffet sushi, not sushi in general. There's a large variety here. You can get sashimi, rolls, or nigiri. The quality of the ingredients is so-so.
The restaurant is large and the tables are set up so that it is easy to accommodate large groups. Of all the things here, I would say that the teriyaki dishes are the best. There are huge trays of both chicken teriyaki and beef teriyaki. Served with vegetables, it's pretty much what you would get at a Japanese fast food restaurant in a mall food court - but all you can eat. The other hot foods (typical fried food in a Asian buffet) are decent.
For the price (~$12 for dinner), the value is so-so.
