I'm going to be visiting Austin next month, and I need to buy a very special birthday cake while I'm there. It's a child's birthday, but there are going to be lots of adults as well, and I am more interested in having an extremely good cake than I am in the decoration. I don't have a particular vision, but perhaps a good French pastry shop? If there is an American bakeshop that happens that makes extremely good fresh-baked cakes I would consider that, but I am hoping for more than just a standard birthday cake. Any suggestions?
