The frozen yogurt at Austin Chill satisfies sweet teeth in a dozen self-serve flavors with a choice of more than 30 toppings. Mosaic walls of teal and white shelter serving stations where treat architects realize their chilly blue prints. Fro-yo varieties ($0.49/oz.) include classic chocolate, cake batter, strawberry, and pecan praline, a favorite solace of nutcrackers after failed auditions for the ballet. Fresh-fruit toppings mingle with crushed candies to adorn frozen treats, sprinkling peanut-butter yogurt with Oreo crumbles, pineapple with gummy bears, or blueberry with a kaleidoscope of Skittles.
