Desire in boy to see galley (7)
I believe the answer is:
kitchen
'galley' is the definition.
(I've seen this before)
'desire in boy' is the wordplay.
'desire' becomes 'itch' (itch is a kind of desire).
'in' indicates putting letters inside.
'boy' becomes 'ken' (**).
'itch' put inside 'ken' is 'KITCHEN'.
'to see' is the link.
(Other definitions for kitchen that I've seen before include "Room with cooking facilities" , "where food is a concern" , "Cookhouse" , "In workplace" , "food prepared here" .)
