I get it - Credit card processing costs. However, as someone traveling, I do not always keep cash on me. They had an ATM inside that charged $2.25 plus my bank's fee and it quickly went from an $8 venture to almost $15 for me and my Son's single scoops.
The ice cream: I like to call myself a Certified Ice Creamologist. The ice cream was good. I had the cookies and cream. You could tell that it was not mass produced and that made me happy.
All in all it was a good experience. Nothing super amazing about it but I'd go back.
