I must have been in a bad mood when I wrote my first review. After being back to Graeter's, I think their ice cream is indeed premium, reflective of the cost.
I had a double-scoop cone; one scoop mint and one scoop some type of cookies-and-cream. It was $7.54 (the cone itself was $1.80, so a cup might have defrayed the cost). I think Graeter's is more satisfying than a comparable yogurt shop. All the associates here are bound for great futures because they seem to genuinely enjoy working with customers.
I'm going to bump an original three-star review up to four; I hope to come back after more visits and promote it to five.
