Crave Frozen Yogurt, Herndon

The idea behind Crave Frozen Yogurt's treats is that you should feel good about craving them—most of their 24 flavors are fat free and have less than 120 calories per serving. Self-serve dispensers let people get their fill of options such as orchard peach or sea-salt caramel pretzel, which can then be customized with more than 60 candy, cereal, and fresh-fruit toppings. Whether getting a full-size or kids-size cup, treats are priced by the ounce and can be enjoyed inside any location's futuristic interiors. One look around a shop yields visions of slate floors, neon-green walls, and white tables recovered from the first Martian soda shop.
