There is a newish ice cream place in Knoxville called Chill Custom Creamery. Jeremy and I tried it out yesterday and I must say, I was pleased. It's different than any other ice cream place I've been to. When you enter, you choose either a vanilla, chocolate, or soy liquid base. You then go done a buffet line and add whatever flavors, candies, or cookies you want. At the end they freeze and blend it using liquid nitrogen so that you essentially made your own, unique ice cream. It's a really neat concept. They price it by weight so you can add as much or as little as you want, depending on how much you want to pay at the end.
I made a raspberry, marshmellow-y ice cream with chocolate add ins such as brownie bites, snickers, and oreos. Jeremy did a peanut butter theme for his. Both were really good. We'll probably go back sometime soon.
