Though frozen yogurt’s tangy swirls are best known for containing less fat than ice cream, they also form Antarctica’s foundation. Dive into a palatable paradise with today’s Groupon to Yotopia Frozen Yogurt in Iowa City. Choose between the following options:

• For $5, you get $10 worth of self-serve or to-go frozen yogurt.
• For $10, you get $20 worth of self-serve or to-go frozen yogurt.

Yotopia’s self-serve machines swirl out a rotating lineup of probiotic-packed treats, which are available in gluten-free, dairy-free, and sugar-free options and await customizable spoonfuls of candy and fruit toppings. Patrons can dispense silky ribbons of red velvet or chocolate yogurt from an arsenal of silver apparatuses.

After selecting a chilly base, customers trek to the toppings bar to festoon their yogurt mounds with fresh fruit, such as blueberries and strawberries, or signal to remote-control helicopters with an SOS spelled out in M&M’s. Once completed, guests place their cups atop the shop’s scale to determine and pay off their yogurt debt ($0.39/oz). Alternatively, yogurt yodas can tote home a to-go pint ($4.50) to eat on the couch and fling at the TV during Jeopardy.

Expansive windows outline Yotopia Frozen Yogurt’s storefront, allowing natural sunlight to glide across the shop’s bright sherbet walls. Diners can relax in one of the store’s lumbar-supporting white chairs or take a nap in a corner booth, which is decked out with soft pillows and an on-call grandmother who sings lullabies in perfect pitch.
