Think you have what it takes to beat one of the best mixologists in Cincinnati? One audience participant at On The Rocks will be selected to challenge Gorilla Cinema's Jacob Treviño in a head-to-head cocktail battle. In this competition, hosted by renowned mixologist Molly Wellmann, you and Jacob will each make a Ramos Gin Fizz—which, as any bartender worth their margarita salt knows, is a challenging drink to perfect.
