Bar Meatball is on a roll in the restaurant’s new subway-tile look food truck, popping up at festivals and food truck hot spots around the ATL. The truck does double duty to crank out some mean ice cream sandwiches. Pick your sides: chocolate chip, oatmeal raisin, peanut butter or double chocolate. For the middle, choose vanilla, peanut butter chip, chocolate or spumoni ice cream. Destined to be summer’s smash hit at $5 each.
