You know your order before you even open the menu. Maybe it's a Margarita with a salted rim, an Old Fashioned that means business, or an Espresso Martini when the night needs a second wind. But what happens when your go-to drink faces somebody else's favorite? The Martini brings old-school swagger, the Mojito tastes like vacation, and the Negroni has a whole army of bitter-cocktail loyalists. From poolside classics to late-night staples, these drinks have completely different reasons to win. Now it's time to settle the bar argument. Pick your favorites in head-to-head matchups and help crown the best cocktail of all time.
