This restaurant was on a segment of Check Please.
Why does this place get so few mentions? It sounds like it is comparable to Swan's. In fact, according to this SF Weekly review
"Roseann Grimm opened it in 1977 ... Coming from a long line of Italian fishermen, with years of restaurant training under the tutelage of the Sancimino family (which owns Swan Oyster Depot), Grimm felt an oyster bar was the natural choice.
"My grandparents ran an oyster house in North Beach, across from Enrico's, and I have pictures of all my uncles in front of our house on Fair Oaks with an ocean's worth of sea bass strung up," Grimm says."
Like Swan's you can buy fresh seafood to take home.
In a 2005 review, Michael Bauer wrote
" I always head for the seafood salads. This is where Anchor really shines.
A generous mound of fresh-picked crab is arranged on greens studded with carrots, tomato and red cabbage ... I prefer the Thousand Island, a dressing I probably wouldn't have anywhere else but Anchor because it goes so well with the crab and the mix of greens"
He also liked the crab cakes.
The handfull of Chowhound mentions over the years are in the first reply.
