I don't know why this place has such bad reviews, but I quite enjoyed my visit here.
My friend was craving Asian food and the huge sign advertising Dim Sum AND Sushi Buffet proved too good to resist. We got seated very quickly and it took a while to get a waiter. After he arrived though, he was friendly and attentive, explaining the options about buffet vs not very clearly.
We all went for the dinner buffet without the upgrade and started with the nigiri combo and some rolls. I was pretty impressed at how fresh the fish tasted and the portion sizes for a buffet. They did scale down the size of the nigiris but also the amount of rice it came with which is great cuz we had room to try other things. The roll with soft shell crab was breaded just right. We got a few of their "pizzas" but did not find those to be worth because there is way too much sauce and rice for the amount of fish they give. We also ordered the ginger scallops which were lightly ginger flavored and fresh.
As far as bang for the buck, my faves were the sashimi selection and nigiris. We tried some other dim sum selections that were pretty good as well but quite filling.
I'd definitely recommend this place for sushi buffet. They don't overdo it with the rice, and they offer a ton of sashimi options. 4 stars!
