Theater lobbies (6)
I believe the answer is:
foyers
'theater lobbies' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for foyers that I've seen before include "Lobbies" , "Entrance areas in theatres" , "Entry halls to theatres or cinemas" , "Entrance halls to theatres" , "Entry areas to theatres" .)
