Pending permits, owner Jacob Irving said Pop Pop’s Dandy Dog food truck will open June 3 at 404 Caroline St., Montgomery. The truck will sell hot dogs, crinkle-cut fries and funnel cake with a variety of toppings. Irving, a high school junior in Montgomery ISD, said the name of the truck comes from the restaurant his grandfather owned in Lewisville in 1985 called Dandy Dog, and he wanted to honor the most inspiring man he knows. 936-228-9984.
