I have reviewed Jeni's in Columbus before, but might as well note that they are as good as ever.
The staff at Chagrin Falls were very friendly and helped my boyfriend through all the options (he had never been to a Jeni's before). He was blown away, of course.
I had the Yazoo Sue, which is a beer-based ice cream with various nuts dusted in rosemary and cayenne pepper. Such a weird taste, but really good. I am a sucker for rosemary anything. The Sweet Potato and marshmallow was also great.
