Gateshead lanes lead to kitchens in the marina (7)
I believe the answer is:
galleys
'kitchens in the marina' is the definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Perhaps you can see an association between them that I can't see?
'gateshead lanes' is the wordplay.
'gateshead' becomes 'g' (head letter of 'gates').
'lanes' becomes 'alleys' (I've seen this in another clue).
'g'+'alleys'='GALLEYS'
'lead to' is the link.
Can you help me to learn more?
(Other definitions for galleys that I've seen before include "Areas for food preparation on ships" , "proofs" .)
