Irish coffee is a cocktail consisting of hot coffee, Irish whiskey, and sugar, stirred, and topped with cream. The coffee is drunk through the cream. The drink was later made famous by Pulitzer Prize-winning "San Francisco Chronicle" columnist Stanton Delaplane, who frequented the Buena Vista Cafe in San Francisco during the 1950s.
