Capitol Hill's mystery soda machine was a Coke-themed vending machine in Capitol Hill, Seattle, Washington, United States that was in operation from at least the early 1990s until its disappearance in 2018. It is unknown who stocked the machine.

This flavor was interesting, to me it smelled faintly like bubblegum but it tasted more fruity, and the aftertaste that lingered in my mouth was like an artificial banana flavor. I'm still not sure how I would describe it, it's very hard to pin down
