A counter-blow (6)
I believe the answer is:
buffet
I believe this is a double definition.
'a counter' is the first definition.
(buffet is a kind of counter)
'blow' is the second definition.
(thesaurus)
(Other definitions for buffet that I've seen before include "Batter - refreshment counter" , "Self-service meal; strike" , "cafeteria?" , "Help-yourself meal - batter" , "Snack bar" .)
