Frozen yogurt is used to delight taste buds, unlike boiling yogurt, which is used to stop invaders from scaling gingerbread castles. Harness the benefits of this powerful treat with today’s Groupon: for $6, you get $12 worth of frozen yogurt, pastries, and coffee at Yogurt Cafe.

The staff at Yogurt Cafe fills self-serve yogurt machines with a menu of flavors that rotate every 10 days. Guests sculpt smooth, spiraling hillocks of frozen yogurt ($0.45/ounce) in flavors such as carrot cake, classic vanilla or chocolate, and mango tango and heap on ornaments from a range of more than 50 toppings. Fresh fruit, candy corn, and butterscotch sauce help hide snowy yogurt peaks from scorned skiers, and the aromas of roasting Caribou coffee ($1.50–$1.70) drift in earthy clouds over mochas ($4.25), which warm up frozen windpipes and sluggish neurons. Sweet teeth sink into baked delights such as raspberry- walnut pastries ($1.99 for three) and blueberry scones ($2.25) to quiet tummies grumbling like Smokey the Bear touring a fireworks factory, and patrons check emails on Yogurt Cafe's free WiFi.
