Fresh Watermelon is a July-and-August shake, and one critic calls it the most polarizing flavor on the menu.

Why is the watermelon shake so polarizing?
Because it is real watermelon, with chunks, juice and seeds. AOL's essay on the shake titled it "doesn't make sense, but it's the only summer taste that matters," and Tripadvisor reviewers have praised it in Newport News, Virginia and Raleigh, North Carolina. One reviewer called it an exquisite blend of vanilla ice cream and frozen watermelon chunks and noted shards of seeds. Another said the watermelon is lightly blended, with small bits left in the ice cream.
