I'm a huge gelato/ice cream fan. When I can't have gelato, my next go-to is Cold Stone! Frozen yogurt just doesn't compare or have any richness in flavor.
Every time I go to Cold Stone (which is more than I care to admit) my absolute favorite item is the Peanut Butter Cup Perfection. Nothing beats the delicious mix of chocolate and peanut butter.
Shakes are really good too. I wish they had a smaller shake size to choose from as I can't even finish their smallest size.
