Very agreeable drink (7)
I believe the answer is:
cordial
I believe this is a double definition.
'very agreeable' is the first definition.
(cordial means agreeable or friendly)
'drink' is the second definition.
(cordial is a kind of drink)
(Other definitions for cordial that I've seen before include "drink with a fruity flavour" , "Hearty - drink" , "stimulating drink" , "Warmly welcoming to the drink" , "Pleasant - soft drink" .)
