Taste, in the buffet (5)
I believe the answer is:
smack
This clue is a double definition.
'taste' is the first definition.
(smack is a kind of taste)
'the buffet' is the second definition.
(thesaurus)
'in' is the link.
(Other definitions for smack that I've seen before include "Hit - drug" , "Sharp blow; sailing boat" , "Slap the fishing vessel" , "Hit - fishing vessel" , "Suggestion" .)
