Some wine for artist in bistro (6)
I believe the answer is:
carafe
'some wine' is the definition.
(I've seen this before)
'artist in bistro' is the wordplay.
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'in' means one lot of letters goes inside another.
'bistro' becomes 'cafe' (I've seen this in another clue).
'ra' put inside 'cafe' is 'CARAFE'.
'for' acts as a link.
(Other definitions for carafe that I've seen before include "Open-topped glass flask" , "Wine-flask" , "Glass bottle for serving wine at table" , "It may provide drink" , "Glass bottle in which wine is served at table" .)
