I am vacationing in the Bay Area/Napa later this year and looking for a good romantic restaurant that is maybe a little out of the way (but not much) and overlooks the Pacific Ocean or has a great view, preferably facing west.
The Ritz in Half Moon Bay is the only one I could think of that might qualify. The food is somewhat standard "upscale" but I didn't find it especially romantic just because it was a bit more corporate than I like.
Heritage House in Mendocino as a view, but has a surprisingly pedestrian wine list (considering the neighborhood) at least provided a fairly decent Merry Edwards Pinot. The menu was hardly exceptional except that what was offered was thoughtfully prepared. The BF started sweetbreads and we were both surprised when only one was served. I had a seafood chowder that was very well done -- not overly thickened but with chunks of potato and nicely complemented with shrimp, scallops, and clams. BF had an oxtail ragout while I chose the duck breast. Mine was highlighted with an accompaniment of a bruleed onion mousse which was the true standout of the meal. Merlot-macerated fruit with a berry sorbet and a white chocolate creme brulee finished the meal, but both deserts were fairly forgettable.
SLRossi is correct and this true for most of the coastal restaurant in California.
Some ideas and romantic is always subjective--
Poggio- in Sausalito, maybe? Not perfect food and maybe someone can comment on any recent visits. Nice view not west, maybe romantic depends on where you sit.
The Caprice- in Tiburon $$$$ - I have never been, search here to see any recent updates.
Since you are heading up North maybe Seaweed Cafe in Bodega.. romantic, a bit out of the way, sorry no ocean view.
When we go and stay in Jenner we like the River's End. Great place to catch the sunset, it's where the river meets the ocean so it's a unsual view. The interior is rather dated 70's but still it can be romantic..and it's casual.
