Ben and Jerry's is by far the best. They have the best selection of flavors and the inside of their store smell amazing. I would literally pay money just to go into their store and smell it.
Cold Stone Creamery is the best! You can put anything from cookies, brownies, candy, etc. in any flavor of ice cream and they mix it up in it and serve it in a chocolate dipped waffle bowl. It is so good. Try it. You will love it. Hope I helped.
