Cambridge college changed meal menu (8)
I believe the answer is:
emmanuel
'cambridge college' is the definition.
(I've seen this before)
'changed meal menu' is the wordplay.
'changed' is an anagram indicator.
'meal'+'menu'='mealmenu'
'mealmenu' with letters rearranged gives 'EMMANUEL'.
(Other definitions for emmanuel that I've seen before include "Boy" , "Messiah's name (Is. 7.14)" , "Lame menu (anag) - Cambridge college" , "The Messiah" , "Man" .)
