“Over the top” is the singular phrase that comes to mind when describing this cash-only spot’s signature mason jars, filled to the brim with milkshakes or aguas frescas, each topped with a mind-melting array of gummy sharks, sour belts, cotton candy poofs, fresh fruit—even whole donuts and ice cream-stuffed cookies. Snacks are equally outlandish: Try the Hot Cheetos topped with Kool-Aid-soaked dill pickles.
