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' (French word for 'in').
'town' becomes 't' (abbreviation for town).
'rejected' shows that the letters should be reversed in order.
'drinker' becomes 'toper' (synonyms).
'toper' in reverse letter order is '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" .)
