Fine time to arrive for food! (4)
I believe the answer is:
feta
'for food' is the definition.
(type of cheese)
'fine time to arrive' is the wordplay.
'fine' becomes 'f' (abbreviation).
'time to arrive' becomes 'eta' (abbreviation for estimated time of arrival).
'f'+'eta'='FETA'
(Other definitions for feta that I've seen before include "Goat's or sheep's milk cheese" , "10 down cheese" , "Greek sheep or goats' cheese" , "White Greek cheese" , "Greek 8 across" .)
