Neptune's Net in Malibu
If you go, realize there are two parts to the place. One part has fried seafood and burgers and it's ok. The other part has steamed and boiled corn, lobsters (pacific and maine), shrimp and crab (local rock, dungeness etc), and a pretty good chowder. This is the part with the better food I think. The location is fun for an "outoftown" drive.
