Demolished hot unrefined food in street (12)
I believe the answer is:
thoroughfare
'street' is the definition.
(I've seen this before)
'demolished hot unrefined food' is the wordplay.
'demolished' indicates anagramming the letters.
'unrefined' becomes 'rough' ('rough' can be similar in meaning to 'unrefined').
'food' becomes 'fare' (fare is a kind of food**).
'hot' with letters rearranged gives 'tho'.
'tho'+'rough'+'fare'='THOROUGHFARE'
'in' acts as a link.
(Other definitions for thoroughfare that I've seen before include "Public road" , "Public way or street" , "Main road" , "Road or path" , "Access - road" .)
