City hair-style of consuming interest (4,3)
I believe the answer is:
bath bun
'consuming interest' is the definition.
The definition suggests a singular noun which matches the answer.
'city hair-style' is the wordplay.
'city' becomes 'bath' (I've seen this before).
'hair-style' becomes 'bun' (hair arranged in ball at back of head).
'bath'+'bun'='BATH BUN'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for bath bun that I've seen before include "Rich, sweet little cake" , "Small cake with spices and fruit" , "Sweet spicy confection" .)
