My girlfriend is taking me on a beer trip for my birthday from So Cal to the Bay Area in a couple weeks. So far, we're hitting up Firestone Walker, Lagunitas, and Russian River. We're staying one night in Paso and two nights in Santa Rosa. Are there any bars, breweries, or stores that are a must-visit while we're up there? The only store we have scheduled is City Beer before we head back down to LA.
