A few lunch cohorts were slumming around Dupont Circle the other day after a meal at Pizzeria Paradiso and we wandered into Starbucks when I noticed they had cupcakes. I tried one that was chocolate cake with chocolate frosting sprinkled with chocolate shavings. It was suprisingly good and moist, and it was only $1.50. They also have a yellow cake cupcake with light icing that looked decent.
It wasn't to die for, but it was pretty good considering the price and the convenience.
