If you think about it, there're really only two kinds of frozen yogurt: great frozen yogurt and bad frozen yogurt. Most of these places buy the same mixes, but the art is in the machines and how well the employees handle them.
Menchies falls under the category of Great frozen yogurt. In Yiddish, a "mench" is "a person of integrity and honor," basically someone who does good deeds. Well great deeds are done at Menchies with rotating selections of delicious frozen yogurt, a clean and cheery environment, and the widest selection of toppings that range from locally grown fruits to Nerds candy. Mmm, I'm craving the red velvet selection as I write!
