The flavor selection is diverse, the space is fun (full of smiling happy teens in a Friday night, so infectious!), and the portions are enormous. It's really good ice cream; some of the best I've ever had (but not THE best). The kids working behind the counter are very nice, too. The only real negative is the location being in a shopping center, otherwise everything about it is great.
If you are a cookie dough fan, Mitchell's is top notch! Also, the Great Lakes porter chocolate chunk is actually made with real porter! It's a really creative and tasty flavor. I get the impression it's hard to go wrong with any flavor here. My wife and will definitely be frequenting.
