Warehouse in French town rejected drinker (8)
I believe the answer is:
entrepot
'warehouse' is the definition.
(type of warehouse or store)
'in french town rejected drinker' is the wordplay.
'in french' becomes 'en' ('in' in French).
'town' becomes 't' (abbreviation for town).
'rejected' is a reversal indicator.
'drinker' becomes 'toper' (synonyms).
'toper' written backwards gives 'repot'.
'en'+'t'+'repot'='ENTREPOT'
(Other definitions for entrepot that I've seen before include "Bonded warehouse; port" , "Storehouse" , "Trading port" , "Import/export warehouse, port" .)
