Approach without a place for meeting (5)
I believe the answer is:
venue
'place for meeting' is the definition.
(I've seen this before)
'approach without a' is the wordplay.
'approach' becomes 'avenue' (both can refer to a road).
'without' is a deletion indicator.
'avenue' with 'a' taken out is 'VENUE'.
(Other definitions for venue that I've seen before include "Something is happening here" , "place to meet" , "We could have a meeting here" , "locale" , "Site for event" .)
