City man at home sent back hot food (9)
I believe the answer is:
edinburgh
'city' is the definition.
(Edinburgh is an example)
'man at home sent back hot food' is the wordplay.
'man' becomes 'ed' (short for edward).
'at home' becomes 'in' (similar in meaning).
'sent back' shows that the letters should be reversed in order.
'hot' becomes 'h' (abbreviation eg on taps).
'food' becomes 'grub' (grub is a kind of food).
'h'+'grub'='hgrub'
'hgrub' back-to-front is 'burgh'.
'ed'+'in'+'burgh'='EDINBURGH'
(Other definitions for edinburgh that I've seen before include "Scottish capital" , "Scottish arts festival city" , "'The Athens of the North'" , "City on the Firth of Forth" , "Auld Reekie" .)
