Meal with no end of wine after theatre (6)
I believe the answer is:
repast
'meal' is the definition.
('repast' can be a synonym of 'meal')
'with no end of wine after theatre' is the wordplay.
'with no end of' means to remove the last letter.
'wine' becomes 'asti' (I've seen this before).
'after' says to put letters next to each other.
'theatre' becomes 'rep' (I've seen this in other clues).
'asti' with its last letter removed is 'ast'.
'ast' put after 'rep' is 'REPAST'.
(Other definitions for repast that I've seen before include "lunch?" , "Feast, meal" , "Something to eat" , "Food - tapers (anag)" , "A meal concerning time gone by" .)
