Menchies Frozen Yogurt-King & University, Waterloo

Some first dates are so magical they’ll change your life, and this was the case for Danna and Adam Caldwell. The lovebirds had their first date at a frozen-yogurt shop where they discovered a mutual passion for frozen yogurt (and each other). In 2007, the now husband-and-wife duo created Menchie’s.

Today, the frozen-yogurt franchise has grown to more than 250 locations around the world, and was ranked the fastest-growing chain in 2010. Each one, adorned with pictures of celebrities enjoying Menchie's treats on their walls, offers an assortment of self-serve yogurt flavours and toppings, which customers can mix into a yogurt cup or waffle bowl. The yogurt is made with fresh milk from Canadian dairy cows; many flavours are nonfat, no sugar added, even vegan.
