I went there for a birthday so we were a group of 8. We waited a bit before we got served. It didn't seem that busy and a few waiters passed by without really acknowledging us. Nonetheless, after we had asked for some beers and placed our first round of orders, the waiter assigned to us did a great job of coming back and asking if we needed anything.
The food itself was excellent. The salmon sashimi were awesome, and really everything else was great. I don't remember what everything was so its hard to give some recommendations, but we weren't disappointed by anything... For an All You Can Eat place, I was very pleasantly surprised.
The price itself was fairly reasonable given that we had some big eaters among us. Its 30 dollars per person though so if you have a very small appetite it might not be worth it...
