I'm not sure who told me their frozen yogurt was better than Red Mango's, but I suspect they're probably on the payroll.
I've been here twice now, and each time, I can't figure out why. It's not like the candy is cheap, or even that good. True, it's a bulk candy store which is nice, but you can get the same exact candies from Walgreens just a few stores down State St.
And the frozen yogurt? Cheaper and with better options down the street as well at Red Mango. I'm appreciative of another place to get it at, but why get it from a place that charges so much? (Full disclosure: I do not work at Red Mango, though my fervent disapproval of Campus Candy's might lead you to think otherwise--it's just that I was really, really underwhelmed by what I had at Campus Candy.)
If you really need the cheap-tasting, bulk candy and the amount you can get at Walgreens is more expensive than what you can find here--excellent! Glad you've found your niche.
For me, I'll stick to Red Mango and others. Not my cup of tea, but it might be yours.
