A friend dined with taste (6)
I believe the answer is:
palate
'taste' is the definition.
(thesaurus)
'a friend dined' is the wordplay.
'a friend' becomes 'pal' (pal is a kind of friend).
'dined' becomes 'ate'.
'pal'+'ate'='PALATE'
'with' acts as a link.
(Other definitions for palate that I've seen before include "A plate (anag.)" , "where taste is considered" , "part of trap" , "relish" , "One may savour" .)
