The SFist has a great post on the different East Bay barbies.

“Walnut Creek Barbie”
This princess Barbie is sold only at the Broadway Plaza Mall. She comes with an assortment of Kate Spade handbags, a Lexus SUV, a long-haired foreign dog named Honey and a cookie-cutter house. Available with or without tummy tuck and face lift. Workaholic Ken sold only in conjunction with the augmented version.

“Berkeley Barbie”
This doll is made of actual tofu. She has long straight brown hair, arch-less feet, hairy armpits, no makeup, and Birkenstocks with white socks. She prefers that you call her Willow. She does not want or need a Ken doll, but if you purchase two Berkeley Barbies and the optional Subaru wagon, you get a rainbow flag bumper sticker for free.
