Friend took food, having sense of taste (6)
I believe the answer is:
palate
'sense of taste' is the definition.
(I've seen this before)
'friend took food' is the wordplay.
'friend' becomes 'pal' (pal is a kind of friend).
'took food' becomes 'ate' (I've seen this before).
'pal'+'ate'='PALATE'
'having' is the link.
(Other definitions for palate that I've seen before include "relish" , "One may savour" , "Sense of taste at roof of mouth" , "Liking" , "where taste is considered" .)
