We went to this place for dinner on a week night. The price for adults is in par with other AYCE sushi restaurants but a little high for kids. The service was not the greatest, but based on my observation of other sushi buffets, I think this is more of a culture thing than a waiter/waitress issue.
One thing you may like or dislike about this place is that they include a 10% tip on the bill, so they have already decided for you what you will be tipping, to me that was in par with the service I received, to some that may not be the case. If you choose to tip more, you do have that option at the register ;-)
Over all, I would go back.
