Dupont in Detail: Artful Lunch on Wheels Posted on May 17, 2013 by Sandy Lee Photos: Sandy Lee During a recent lunch break, I happened upon a couple of food trucks in Dupont Circle. No big surprise, food trucks are as common as taxicabs. However upon closer inspection of the menu . . . The Calder Ficelle was indeed a work of art. Forgive me for not taking a picture of it before it was so hastily consumed.
