Supplier of food from rocky terrace (7)
I believe the answer is:
caterer
'supplier of food' is the definition.
(I've seen this before)
'rocky terrace' is the wordplay.
'rocky' indicates an anagram.
'terrace' anagrammed gives 'CATERER'.
'from' is the link.
(Other definitions for caterer that I've seen before include "Person who supplies food for social events" , "Food and drink supplier" , "Someone needed for party" , "Provision supplier" , "Provider of food and drinks" .)
