Pub found by green, say, showing distinctive features of a place (5,6)
I believe the answer is:
local colour
'distinctive features of a place' is the definition.
(colour can mean the atmosphere of a place)
'pub found by green say' is the wordplay.
'pub' becomes 'local' (one's local pub).
'found by' is a charade indicator (letters next to each other).
'green say' becomes 'colour' (greening is a kind of colouring).
'local'+'colour'='LOCAL COLOUR'
'showing' acts as a link.
(Other definitions for local colour that I've seen before include "regional character" , "A place's characteristics" .)
