Sonic offers a secret menu item known as the key lime pie shake, which is created by customizing a cheesecake shake with lime syrup and graham cracker crumbles. Customers can enhance their shake with whipped cream and a cherry. Some patrons have reported challenges ordering this item through the app or convincing staff to prepare it. Alternatives include using a vanilla shake for a milder flavor or a twisted lime cream slush for a refreshing twist.
