Fine quarter for banquet (5)
I believe the answer is:
feast
'banquet' is the definition.
('feast' can be a synonym of 'banquet')
'fine quarter' is the wordplay.
'fine' becomes 'f' (abbreviation).
'quarter' becomes 'east' (I've seen this in other clues).
'f'+'east'='FEAST'
'for' is the link.
(Other definitions for feast that I've seen before include "lots of food" , "Junket" , "Grand meal" , "Lavish meal" , "entertainment" .)
