I am rating this business solely on the quality of their cupcakes. As others have said, they are often closed during their normal business hours, but the cupcakes are definitely worth the hassle of trying to find a time when they are open.
First, let me say that their frosting and cake are both superb. The chocolate frosting on Vanilla cake is my absolute favorite. My Norwegian grandma made a (from scratch) yellow cake with (also made from scratch) chocolate frosting. This cupcake reminds me of my childhood favorite at grandma's house! My kids are always trying new flavors... and they are always happy with their choices. My mom's favorite is the peanut butter, and my husband loves the German Chocolate.
Their rivals up the street might be busier, but these cupcakes can't be beat. This is my new place for a sweet treat!
