Good to get massage and something to eat (4)
I believe the answer is:
grub
'something to eat' is the definition.
(grub is a kind of food)
'good to get massage' is the wordplay.
'good' becomes 'g' (abbreviation).
'to get' is a charade indicator (letters next to each other).
'massage' becomes 'rub' (rub can mean to massage).
'g'+'rub'='GRUB'
'and' acts as a link.
(Other definitions for grub that I've seen before include "Slang food for worm-like larva" , "Food (informal)" , "ferret > eats" , "Dig - maggot - food" , "Beetle larva" .)
