Festival to enjoy with artist in sweet bar? (5,4)
I believe the answer is:
mardi gras
'festival' is the definition.
(Mardi Gras is an example)
'enjoy with artist in sweet bar?' is the wordplay.
'enjoy' becomes 'dig' (to dig can mean to appreciate or 'get').
'with' means one lot of letters go next to another.
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'in' is an insertion indicator.
'sweet bar?' becomes 'Mars' (Mars bar - sweet chocolate bar).
'dig'+'ra'='digra'
'digra' put into 'mars' is 'MARDI GRAS'.
'to' is the link.
(Other definitions for mardi gras that I've seen before include "Carnival (day)" , "Revelry celebrating Shrove Tuesday" , "The lead up to fast" , "Shrove Tuesday festival" , "Time for carnival" .)
