Though frozen yogurt's tangy swirls are best known for containing less fat than ice cream, they also form the country of Antarctica's foundation. Dive into a palatable paradise with today's Groupon: for $3, you get $6 worth of frozen yogurt at Top This! Frozen Yogurt in Oceanside.

Inside Top This! Frozen Yogurt’s colorful, music-filled shop, guests decorate cups with dollops of healthy, chilly dessert sprinkled with delicious toppings. Fro-yo choices rotate daily, drawing from a lineup of more than 100 kosher flavors—treat seekers can savor creamy bites of premium options such as german chocolate cake or banana cream pie, or try a tart variety that puckers mouths faster than a make-out session with a lemon. Fruity, dairy-free sorbets tango with taste buds, and bowls of piña colada yogurt from the no-sugar-added menu simulate spring break without leaving tan lines on your tongue. Settle persnickety stomachs with four Activa flavors, including vanilla, peach, blueberry, and strawberry. Rather than venturing outside to milk a passing rainbow, patrons can find color for their creation by choosing from more than 40 toppings, such as Oreos, peanuts, and Cap’n Crunch cereal, then visit the weigh station to make payment before indulging ($0.41/oz.). Top This! also serves yogurt-filled cookie sandwiches ($2.50 each) and silences grumpy tummies with yo-pies ($12.95/2 lbs.).
