A friend of mine is looking to get a topsy turvy cake for a birthday--just a small one (2-tier--more for the "look I got you a topsy turvy cake like you like" not for the "it can feed everyone" aspect). Anyone know of a good bakery in SF that would work? They are in the City, so anything further than Berkeley might be too far East, and doubt they'd go down the Peninsula...maybe Marin?TIA!
