We had planned on a stop in Guerneville for lunch, but hadn't decided where to go. My husband is a beer lover, so I asked our GPS for any breweries en route, and we were directed to the Stumptown Brewery. It's a dive, but the beer was good and I can honestly say they served the best hamburgers we've had in any restaurant anywhere. The patties were hand-formed just before cooking, they were huge, thick and juicy, cooked medium-rare as requested, and absolutely fresh. I don't remember the price, but it was less than $10. Bay Area people, it's worth the drive!
