For an all you can eat buffet, its not the worst I've eaten at. Its about the same as any other all you can eat Chinese place in Phoenix.
It can be a hit or miss, but as my father likes it so I tend to still go. Though every time I find something I like, they take it off the buffet the next time I go. When they had the Mongolian Pork or Bean Sprouts were my favorite times.
Sushi bar is included, how much is on it depends. I've seen it loaded down and I've seen it nearly empty. When they are out of the only kind I like, I asked and they made it for me.
One of the wait staff is very nice, she'll do magic tricks at the table when its slow. Also, when I do eat the crab legs they have brought me lemons every time I've asked. They are often small, but it is all you can eat and that's typical at most of the other buffets I've been to. I have seen moderate size snow crab legs there, if you get them when they first are bringing out the dinner items.
