Though spoons are notoriously handy for lifting amorphous food, they're quickly being replaced by forks, knives, and bread rolls in the majority of first date dinner gimmicks. Put spoons back on the utile utensil list with today's Groupon: for $4 you get $8 worth of frozen yogurt and toppings at Nuberri.

A frozen yogurt shop with a hands-on twist, Nuberri allows patrons to create their own yogurt and topping concoctions. The menu boasts 20 active-culture yogurt flavors daily, each featuring heart-warming subheadings such as non-fat, low-fat, reduced fat, and no sugar added. Flavors start with traditional Vanilla Bean and Swiss Chocolate, but the more adventurous yogurt connoisseur can try out tastes like Banana Pudding, Root Beer Float, and Cake Batter. Four-ounce servings contain between 100 and 200 calories, encouraging stomachs to expand to a size much larger than their northerly pupil neighbors. Regardless of which gurt gets the nod, more than 60 toppings—ranging from fresh cut fruit to candy to pretzels to key lime sauce—await madly sweet scientists. Post-construction, the helpful staffers weigh the creations—toppings and all—to the tasty tune of $0.45 per ounce.

The colorful toppings in the bowl are not the only things giving off a fun, fresh vibe at Nuberri. The space is as clean, bright, and open as the eyes of a baby sunflower that's learning about photosynthesis for the first time. The shop stays open seven days a week, keeping the cool hits coming as late as midnight on Fridays and Saturdays.
