A city hairstyle, or something to eat (4,3)
I believe the answer is:
bath bun
'something to eat' is the definition.
I can't tell whether this definition defines the answer.
'a city hairstyle' is the wordplay.
'a city' becomes 'bath' (I've seen this before).
'hairstyle' becomes 'bun'.
'bath'+'bun'='BATH BUN'
'or' is the 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" .)
