Bear to the left, reaching city's stall at fair (6)
I believe the answer is:
hoopla
'stall at fair' is the definition.
(stall at a funfair)
'bear to the left reaching city's' is the wordplay.
'bear' becomes 'pooh' (Winnie the Pooh).
'to the left' says the letters should be written in reverse (reading from right to left).
'reaching' is a charade indicator (letters next to each other).
'city' becomes 'LA' (Los Angeles).
'pooh' backwards is 'hoop'.
'hoop'+'la'='HOOPLA'
(Other definitions for hoopla that I've seen before include "Fairground stall attraction" , "game in which all-round achievement is rewarded" , "fair prize at this" , "Game in which rings are thrown over objects in order to win them" , "Throwing event at a fair" .)
