Fish Mike leaves in drawing-room (5)
I believe the answer is:
salon
'drawing-room' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for salon that I've seen before include "Elegant room is great house for entertaining" , "Loans given to hairdressing establishment" , "Literary gathering" , "Parisian art exhibition" , "Elegant room for receiving guests" .)
