Does this brand taste as good as it looks?

A client referred me to Sprinkles Cup Cakes this morning.
I have to admit I am very impressed with the sense of design to this product. I understand that it costs about $3.25 per cupcake. They come in individual boxes. The boxes are superbly designed. The dozen trays are also well designed. The stores are outstanding. Everything about this product is high end.

I'd love to know from any out there in the blogesphere if you have ever experienced the store? What was the experience like? Does it compliment the esthetic? It has been featured on most popular televison buzz shows. I wonder if it has staying power, or it this month's flavor?
