The Doubletree's “Cookie CAREavan” in action. (Doubletree Hotel)

Looking for something sweet during your lunch break today? Head over to Union Station, where the Doubletree hotel’s cookie truck is distributing free chocolate chip cookies until 6 p.m. The promotion, called the “Cookie CAREavan Tour” is part of a 10-week, 50-city tour to celebrate the 25th anniversary of the hotel’s famous chocolate chip cookie.

If that’s not enough food from trucks for you, pencil in a long lunch tomorrow and head to the Bullpen for Truckeroo, the first of a planned monthly gathering of over 20 trucks near the Nats Park.
