There was recently a thread on the Food Board about this topic. It is still on the first page over there so it could give you some immediate thoughts on where to go.
Benzinger (not Beringer, Benzinger) ... extremely nice winery, wine club is well worth joining (we're members) and they teach you a lot of interesting stuff about the way they run their farm and vineyard.
+1 on Benziger, we enjoyed that one. Also, we did the wine/food pairing at the Mayo Room and really enjoyed it. Something different and the chef was the one to serve us so it was neat to have him there to explain his choices.
