Vanilla Soft Serve with Rainbow Sprinkles from the Cozy Cones in DCA $5.79 We love the soft serve at the Cozy Cones in DCA. This tastes so good no matter the day! Recently noticed they are offering a few topping options again after a long time of not offering them. Cookie crumbles ($.99), chopped peanuts ($1.49), and rainbow sprinkles ($1.49) are the three toppings available right now.
