Cupcakes: Can’t stop, won’t stop. But just when you think Atlanta might be sick of frosting, another Crayola-colored cupcake bakery opens it doors. A chain out of Beverly Hills, Sprinkles at Lenox Mall is the latest of the batch. On a recent visit I had hoped to grab a dozen for the office, but I burned those plans when the clerk said that a dozen costs $42. Between the ten or more employees shuffling behind the counter, the swirly mountain of icing on each cake, and the cupcake ATM machine that operates 24/7, running this place isn’t cheap. Somebody has to pay.
