The fall chill was dispelled in DUMBO yesterday by the raging grills at the 2008 Vendy Awards. The highlight of this year's competition was a new category for dessert trucks. Wafels and Dinges didn't show, but artisanal-ice-cream guy Ben Van Leeuwen battled the Treats Truck and Dessert Truck for bragging rights. Grub Street's Alexandra Vallis was on hand to speak to some of the competitors, question decisions by judges Eater X and Calvin Trillin, and see who took home street food's highest honor.
