Taylor's Refresher- Napa Valley

This is a classic Drive In     http://www.gotts.com/   You can find it up in Napa which is the best spot to go to and a "must do" when you're in the area.  If you're desperate, there's a location at the Ferry Building in San Fran that will satisfy your taste- somehow it's just not as good as sitting on the side of the road in St. Helena and having this amazing burger.
