Chocolaty coffee drink (5)
I believe the answer is:
mocha
'chocolaty coffee drink' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for mocha that I've seen before include "Coffee drink" , "Deep brown; a fine coffee" , "Fine-quality coffee" , "Yemeni port; type of coffee bean" , "Coffee flavour" .)
