We visit some of the world-class eateries that satisfy the sweet cravings of Washington, D.C.'s power brokers. First stop: GBD, which stands for "Golden Brown Delicious" - the perfect way to describe the unique doughnuts at this new hotspot. We'll visit Cupcakes Actually, which stocks its shelves with 10 varieties of this sweet treat daily, including its signature dipped cupcakes. And we'll sample the refreshing artisan gelato at Dolcezza, which combines local ingredients, old-world methods, and innovative flavors.
