Dated American cocktail (3-9)
I believe the answer is:
old-fashioned
This clue is a double definition.
'dated' is the first definition.
(thesaurus)
'american cocktail' is the second definition.
(type of American cocktail)
(Other definitions for old-fashioned that I've seen before include "Outmoded - 1 down" , "Passe; whisky cocktail" , "Demode" , "Pass" , "Outdated" .)
