Cafeteria is hit (6)
I believe the answer is:
buffet
This clue is a double definition.
'cafeteria' is the first definition.
(thesaurus)
'hit' is the second definition.
(buffeting is a kind of hitting)
'is' acts as a link.
(Other definitions for buffet that I've seen before include "Refreshment bar" , "self-service place" , "Self-service meal - pound" , "Meal at which people help themselves" , "Cold table" .)
