Would love to... just wasn't sure if there was interest since I am on the west coast and most of you all are east coasters. Here are my two top favorites right now:
The Press Club in San Francisco, here is a link:

This is Napa valley comes to downtown San Francisco. A lovely way to bring Napa to the tourists of the city who do not have the time or means to travel up to Napa. My favorite two vintners here are Chateau Montelena and Pahlmeyer. Chateau Montelena is a drinking wine and their estate Cab cannot be beat!!! Pahlmeyer is more of a pairing wine for fine foods that are rich in fats and flavor, it has a very strong back bone, I did not care for it as a plain drinking wine but loved it with a nice rib eye.
My second favorite wine cooperative which I only recently discovered is:
http://www.maisonry.com/
Not only does Maisonry have wonderful wines but the outdoor fire pit and the charm and hospitality of the owner is quite the experience. Although the owner of Maisonry favors the Blackbird vineyard I personally fell in love with the Brown Estate Zinfandel. This is not your average zin that is way too fruit forward like some of the vineyards are making it now. It has a lot of rich spicy flavor and a fabulous flower pop.
If you would like to know more I have just returned from a week in Napa and toured and tasted many wines, I also came home with a few secrets!!!
