Chuck Berry's empty foyer (5)
I believe the answer is:
lobby
'foyer' is the definition.
(I know that foyer can be written as lobby)
'chuck berry's empty' is the wordplay.
'chuck' becomes 'lob' (I've seen this before).
'empty' suggests removing the centre.
'berry' with its centre removed is 'by'.
'lob'+'by'='LOBBY'
(Other definitions for lobby that I've seen before include "Vestibule" , "Group seeking influence" , "Entrance room" , "Shy" , "Entrance hall - seek to influence" .)
