ISO - Ace of Cakes in East Bay
If you're looking for a theme cake (as I presume from the Ace of Cakes reference), Katrina Rozelle in Rockridge might work. Here are some pictures on her website: http://www.katrinarozelle.com/Pages/s...
If you just want something tasty and pretty, I'd try Crixa (across from Berkeley Bowl): http://www.crixacakes.com/archives/ca...
Or La Farine (in Rockridge):
Well I didn't have one the those birthdays when I got a cake, but I got one for another party. I went to Montclair Baking. The owner won a contest on one of the Food Network cake contests. I wanted a really dark rich chocolate cake with a decorative icing and they delivered. Here is their website: http://www.montclairbaking.com/
