No. Where'd you get a California in SF?
San Francisco "Super" burritos are everything you could possibly put in a burrito: rice beans cheese sour cream guacamole salsa meat etc etc.
California burritos are usually meat cheese guac and salsa, with potatos replacing the beans and rice.
Someone correct me if I'm wrong, but I've never had a "California" burrito in the Mission. We could start arguing about which is better, but really I don't see why we can't like both...
