About the meal out, say it's an impasse (9)
I believe the answer is:
stalemate
'an impasse' is the definition.
(synonyms)
'about the meal out say' is the wordplay.
'about' indicates putting letters inside.
'out' indicates an anagram (out can mean wrong or inaccurate).
'say' becomes 'state' (synonyms).
'meal' anagrammed gives 'lema'.
'lema' inserted into 'state' is 'STALEMATE'.
'it's' is the link.
(Other definitions for stalemate that I've seen before include "Unresolvable position" , "Blocked position" , "Deadlock, impasse" , "Inconclusive result" , "where moving is impossible" .)
