Whiskey cocktail ... or where it was invented

I believe the answer is:

manhattan

(Other definitions for manhattan that I've seen before include "area of New York City" , "Vermouth and whisky cocktail - New York borough" , "NY borough" , "Cocktail consisting of whisky, vermouth and bitters" , "Vermouth and whiskey, with a dash of bitters" .)

I've seen this clue in The New York Times.
