"Writer H.L. Mencken called the martini “the only American invention as perfect as the sonnet.” It’s no surprise this classic cocktail was born in a New York hotel bar; like Manhattan, a good martini is strong, dry, and smooth. A bartender at the Knickerbocker named Martini di Arma di Taggia is said to have served hotel regular John D. Rockefeller the drink for the first time."
