Street, a meeting place (6)
I believe the answer is:
avenue
'street' is the definition.
(I know that avenue is a type of street)
'a meeting place' is the wordplay.
'meeting place' becomes 'venue' (place for a meeting).
'a'+'venue'='AVENUE'
(Other definitions for avenue that I've seen before include "suburban street" , "A broad thoroughfare as in New York" , "Broad tree-lined road" , "A broad wide street" , "Thoroughfare, boulevard" .)
