Takes a set dish? (4)
I believe the answer is:
eats
'takes' is the definition.
(eating is a kind of taking)
'a set dish?' is the wordplay.
'dish?' indicates anagramming the letters (dish can informally mean to destroy).
'a'+'set'='aset'
'aset' is an anagram of 'EATS'.
(Other definitions for eats that I've seen before include "Victuals" , "Food (informal)" , "Provisions" , "Commonly, they eliminate" , "Sate (anag.)" .)
