Drink date in sporting venue (6,5)
I believe the answer is:
squash court
'sporting venue' is the definition.
(I've seen this before)
'drink date' is the wordplay.
'drink' becomes 'squash' (I've seen this before**).
'date' becomes 'court'.
'squash'+'court'='SQUASH COURT'
'in' is the link.
(Other definitions for squash court that I've seen before include "match venue" , "sporting venue" , "Indoor space for a racket sport" , "Scene of ball game" , "Room for game" .)
