Headed here with my family on the day after New Year's Eve for the lunch buffet. We were seated very quickly without a reservation. We came in what seemed to be the lunch rush (around 2pm) and our first round of orders came in reasonably quickly (items appeared one by one over the course of 10-20 minutes), and once the restaurant had settled down around 3pm food came almost immediately.
The waitresses are mostly young students, but very polite and professional. Service was excellent (you just had to be a little more proactive to get their attention when the place was busy).
The food itself was excellent and always beautifully presented, especially for an all-you-can-eat place and definitely the best value for the price that I've ever seen ($15/person for the lunch buffet on a holiday). Portion sizes are good for sharing and small enough that you can sample a bit of everything, so don't go overboard ordering 2 or 3 of the same item before you've tried a couple of different things. They also levy a charge on any uneaten food, which is completely reasonable given the quality of the items available on the lunch buffet menu.
Favourites: rock shrimp, volcano roll, eel roll, beef teriyaki, banana tempura. But everything we ordered was yummy.
Add in the tasteful modern décor, interesting wall art, and clean, spacey tables and booths...can't be beat!! Give this place a go.
