The Hoffman House Hotel maintained New York’s best bar at a time when New York had nothing but great bars. Located at Broadway and Twenty-second Street, across from the très swank Madison Square (the park, not the hockey venue), it pulled in a strictly A-list clientele until it got hauled down and replaced with an office building. That was in 1915. Their version of the Martini is one of the most suave known to science.
2 ounces gin, preferably Plymouth
1 ounce white vermouth
2 dashes orange bitters
To finish: orange peel
Stir and strain into a chilled cocktail glass; twist orange peel over the top.
