What delicious seafood buffets are there in Beijing?

I had a seafood buffet in Haitang. There are many kinds of seafood, which are fished and cooked now. One hot pot for each person, with fish, shrimp, crab, abalone and shellfish. Abalone is very good. Although it is not big, it is fresh and tender. The food in the Japanese food district is a bit poor, but it used to be dominated by seafood. There are more than ten kinds of fruits to choose from in the fruit area. Mango and Elizabeth melon are the best. There are all kinds of drinks, Huiyuan juice, Arctic Ocean soda and so on.
