Dish gin out at the party (7)
I believe the answer is:
shindig
'the party' is the definition.
(shindig is a kind of party)
'dish gin out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'dish'+'gin'='dishgin'
'dishgin' is an anagram of 'SHINDIG'.
'at' acts as a link.
(Other definitions for shindig that I've seen before include "wild party" , "commotion" , "Hooley" , "Large and noisy party or quarrel" , "Hidings (anag) - party" .)
