I've tried other cupcake bakeries like Sprinkles and Kara's Cupcake here in the bay area. Although this place lets you customize your cupcake with different fillings and frosting but the flavor can't compete with Sprinkles.
I had their red velvet with vanilla bean fillings with vanilla buttercream frosting. my husband tried the red velvet with coconut filling with white chocolate frosting. When we bit into it, we couldn't find the filling. One good this about it is that the cake was nice and moist. For $3 a piece, it wasn't worth it.
