I tried their all you can eat menu at night.
It's about $22 and with the coupon, I think it comes down to about $18 per person.
Given the price, I think the food is decent. It's all you can eat, so food quality is not that great. There are still lots of choice for sashimi and sushi. They also have a special dish that you can't find else where, but only limit 1 per person. There is no oyster at all in their menu though.
I probably won't go back again though. There are alot other choice for japanese food in richmond.
I agree with starstar, the food quality is not that great. I'm not sure about other times, but the day I went, their sushi and sashimi, doesn't feel very fresh.
