A friendly drink (7)
I believe the answer is:
cordial
I believe this is a double definition.
'a friendly' is the first definition.
(thesaurus)
'drink' is the second definition.
(cordial is a kind of drink)
(Other definitions for cordial that I've seen before include "Friendly; fruit drink" , "7 [HEARTY]" , "Warmly welcoming to the drink" , "Hearty - drink" , "Agreeable - drink" .)
