We used 3 coupons from Groupon for our 3 visits. First time about 3 months ago was the best and each subsequent time it was getting worst in services and food as well. Good thing we only paid 48+taxes+tip (decreased from 12 to 10 to 7%) as services were really getting bad. For example: wrong quantity brought out. After bringing it to their attention we would have to ask different server about 4 times each issue. Seaweed salad decreased substantially, it became more salad than seaweed. Only chicken skewer were good but if you count they are short changing the order for example you order 2 unit that would equal to 8 pieces but they only give you 5 skewers. That happen for practically every large quantity order. We were planning to come back just for buffet but not now. We saw some great review for another sushi buffet near Pacific Mall and tried the Bentonville box today and found their food is much more fresh and carefully made. This is still a decent place for after Ontario Science center visit to end the day with if you are from out of town.
