Cool picture leading creative artist restored: Nude Enjoying Dish (6,3,5)
I believe the answer is:
chilli con carne
'dish' is the definition.
(I've seen this before)
'cool picture leading creative artist' is the wordplay.
'cool' becomes 'chill' (synonyms).
'picture' becomes 'icon' (icon is a kind of picture).
'leading creative artist' becomes 'carne' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'chill'+'icon'+'carne'='CHILLI CON CARNE'
'restored nude enjoying' acts as a link.
This may not be right. Some or all of it may be part of another bit of the clue.
(Other definitions for chilli con carne that I've seen before include "Spicy stew" , "Spicy dish" , "meal" , "fare" .)
