I'm in charge of the birthday cake for my sister this weekend. Seeing as how I never buy cakes and don't know where the best bakeries are, I was just going to drop by balducci's and pick up somthing pretty. But I have a feeling that there's something better out there than balducci's. Anyone have recommendations? She'd prefer a black forest cake, but it doesn't HAVE to be black forest. Price wise, I'd like to spend $15-20 for a decent sized cake (serving about 6).
