One Barking High Street (6)
I believe the answer is:
setter
'one barking' is the definition.
(I've seen this before)
'high street' is the wordplay.
'high' indicates an anagram (like drunk).
'street' with letters rearranged gives 'SETTER'.
(Other definitions for setter that I've seen before include "One barking" , "puzzle constructor" , "Thematic type [DOG]" , "Crossword creator" , "Bird trained to scent game" .)
