Meeting place and street bar opening (5)
I believe the answer is:
venue
'meeting place' is the definition.
(place for a meeting)
'street bar opening' is the wordplay.
'street' becomes 'avenue' (avenue is a kind of street).
'bar opening' means to remove the first letter (the word except or bar its opening letter).
'avenue' with its initial letter taken away is 'VENUE'.
'and' is the link.
(Other definitions for venue that I've seen before include "Appointed place or location" , "Location for a performance" , "Something is happening here" , "place to meet" , "Location of meeting" .)
