Hi, V., and congratulations to your daughter!
There are two bakeries that do fantastic cakes off Anderson Mill Road at 183. One is called Dream Bakery. They did a great "Bob the Builder" cake for my son's birthday and it was fantastic -- great taste and great decor details. They have some gorgeous cakes in their portfolio, their prices are reasonable, and the woman who runs the bakery is incredibly nice.
Just a few doors down is Cakes, Chocolates and More, which is also run by an incredibly nice woman who does sculptural cakes that are visually stunning. I got a shark-shaped batch of cupcakes from her one year for my other son's party and they were delicious and decorated with lavish detail. This bakery's cakes are more expensive than Dream Bakery but if you want something the guests will talk about for years, this would be the place to go.
Good luck with your planning!
