Chanel with a drink (5)
I believe the answer is:
cocoa
'drink' is the definition.
(I know that cocoa is a drink)
'chanel with a' is the wordplay.
'chanel' becomes 'coco' (I've seen this before).
'with' is a charade indicator (letters next to each other).
'coco'+'a'='COCOA'
(Other definitions for cocoa that I've seen before include "Kind of chocolate drink" , "Popular chocolate drink" , "drink from beans" , "brown powder" , "Reddish brown" .)
