Stole material from Corfu restaurant (3)
I believe the answer is:
fur
'stole material' is the definition.
(I've seen this in another clue)
'from corfu restaurant' is the wordplay.
'from' indicates the answer is hidden within the clue.
'FUR' is hidden within 'corfu restaurant'.
(Other definitions for fur that I've seen before include "Hard water pipe coating" , "Animal-skin coat" , "Hair covering animal's body" , "Hairy animal's coat" , "Coating in kettle" .)
