It's not a seafood buffet and crab legs aren't cheap. There are plenty of places with all you can eat crabs it's just more expensive. Grand East is Chinese/Japanese cuisine, the fact that they even have crab legs is a bonus.

The prices are the same weekdays and weekends.

Yuppers

I have not seen roasted duck there.

No, this is a buffet however there are a lot of places in the area deliver
