From CA?? Where the hell do they think hippies were invented?? 
Pioneertown is up by Yucca Valley in the sticks, did a day trip to Joshua Tree from there. It was built for TV and movies after WWII. Instead of fronts, it is made of buildings. Cisco Kid and such were filmed there.
Pappy and Harriets is an indie place for musicians. The web site points out that Robert Plant and Eric Burdon have played there along with other notables. Was a decent meal too. It was on Antony Bordain's last show that we watched, so it will be on the tourist/foodie trail now.
Hippies were invented in the Bay Area, yes.
