Maybe someone who has tried Corks restaurant at the Russian River Vineyards can give an opinion. We stopped by there for wine tasting a couple of weeks ago but didn't eat. The wines were great, they were very friendly and it is a very pretty property. This is right in Forestville.
If they don't mind a little driving, Bistro des Copains in Occidental is a beautiful little spot, we had a great dinner there and it has been recommended here several times.

This should probably be on the SF board. But, I'll try to sneak this one through. Check out the Farmhouse. It's pricey, but very good and a different kind of place. The girls will love it.
