Only thing I have in my notes for Point Arena is the Pier Chowderhouse and Tap Room
About 15 mi south in Gualala are two great spots, Pangea and St. Orre's (make sure owner/chef Rosemary Campifornio is there). About the same distance to the north Queenie's in Elk is a good spot for breakfast. La Petite Rive is just north of there in Little River, haven't been yet but seems to get good reviews on this board.
