Bear going round coastal city provides fair game (6)
I believe the answer is:
hoopla
'fair game' is the definition.
(game played at a fair)
'bear going round coastal city' is the wordplay.
'bear' becomes 'pooh' (Winnie the Pooh).
'going round' is a reversal indicator.
'coastal city' becomes 'LA' (Los Angeles).
'pooh' back-to-front is 'hoop'.
'hoop'+'la'='HOOPLA'
'provides' is the link.
(Other definitions for hoopla that I've seen before include "Game in which rings are thrown over objects in order to win them" , "needless commotion" , "Fairground stall attraction" , "Fairground game; great excitement" , "Fairground throwing game" .)
