I have loved the Cake Bake shop the two times I've been (once at each shop). Yes, the prices are high, but the cakes I've tasted have mostly been really good and the servings were enough for two people to share. Plus, as was mentioned before, they use the highest quality ingredients and got a huge bump several years ago from Oprah's being a fan, increasing their ability to set themselves apart from other bakeries and thus command higher prices. Oprah's magazine is how my step-mom found and fell in love with them.
Even if I didn't like their cakes, I would still be a huge fan. When my step-mom was ill from cancer, in the last few months of her life, she was craving something from the Cake Bake Shop. My dad called them up and they sent several slices to my step-mom from Indianapolis down to Lanesville, Indiana (close to Louisville, KY). I'm sure he paid well for it, but I also know they sent more than he requested, along with a very sweet note. They'd really have to flub something up bigtime for me to not visit them any chance I get.
That said, I'm not sure how good a fit they are for the Boardwalk, but I guess we'll see!
