At Yo Cool Frozen Yogurt, panels in the bright-blue walls reveal shiny chrome yogurt dispensers. Pull down a handle and fill your cup with rotating flavors that might include peanut butter, strawberry shortcake, and dutch chocolate. Then go wild and pile on as much candy, fresh fruit, and syrup toppings as your sweet tooth can handle. Mix angel-food-cake frozen yogurt with peppermint syrup, or hide gummy worms in your cake-batter yogurt. To combat the chill of your frozen dessert, pair it with a hot english-toffee coffee, apple cider, or chai latte, or just zip up your parka before every spoonful.
