Food's beautiful, we hear (4)
I believe the answer is:
fare
'food's' is the definition.
(fare is a kind of food)
'beautiful we hear' is the wordplay.
'beautiful' becomes 'fair' ('fair' can be similar in meaning to 'beautiful').
'we hear' indicates a 'sounds like' (homophone) clue.
'fair' is a homophone of 'FARE'.
(Other definitions for fare that I've seen before include "diet" , "Food for the table" , "Food for the cost of a journey" , "Cost of travel" , "what the commuter will pay" .)
