iCream Is an ice cream shop located in Chicago's trendy Wicker Park neighborhood. There are a few other locations but this one is the original. It is the most unique ice cream shop I've been to and there is one reason, nitrogen! iCream makes all their ice cream by using an instant freezing nitrogen technology. I'm not sure about how it works but it is really cool to make your own ice cream and see it be formed right in front of you. They have frozen yogurt, pudding, shakes and sorbet that can also be made right before your eyes.
