Blue Lagoon has become my go to place for dim sum. Unlike a lot of large dim sum restaurants, the dim sum does not come around on a steam cart. You order what you want, they cook it and bring it out for you fresh. From 9 AM to 11 AM (not sure if this is true on weekends) the dim sum is at a discount price, but come before 11 as I have seen lineups by 10;45. I am usually one of the few non-Chinese customers there and I believe that Blue Lagoon's popularity with Chinese customers is a plus.
I have not tried it for dinner; however, the fish tanks in the entry contain an impressive array of huge Alaska King Crabs, 5 pound lobsters and live fish. Obviously, the seafood served for dinner is quite fresh.
