Oktoberfest at Fairplex Home of the Los Angeles County Fair, the Fairplex turns into a German wonderland for Oktoberfest every Friday and Saturday in October with Bavarian music, beer and plenty of chicken dancing. Sink your teeth into bratwurst, knockwurst and sweet corn while knocking back authentic German suds at this 21-plus event with DJs, oompah bands and the Das Kär Show, which will bring over 40 Volkswagen Beetles and other German-made autos to the Fairplex grounds.
