Street not a meeting place (5)
I believe the answer is:
venue
'meeting place' is the definition.
(place for a meeting)
'street not a' is the wordplay.
'street' becomes 'avenue' (avenue is a kind of street).
'not' is a deletion indicator.
'avenue' with 'a' removed is 'VENUE'.
(Other definitions for venue that I've seen before include "Place for organised event" , "Location for a performance" , "Meeting-place" , "Here we gather" , "Event location" .)
