Head honcho should get the best fruit (3,6)
I believe the answer is:
top banana
'head honcho' is the definition.
(I know that top banana is a type of head honcho)
'the best fruit' is the wordplay.
'the best' becomes 'top' (top can mean the very best).
'fruit' becomes 'banana' (type of fruit).
'top'+'banana'='TOP BANANA'
'should get' is the link.
(Other definitions for top banana that I've seen before include "figurehead?" , "Star entertainer" , "Most important person in group (informal)" , "Big cheese" , "Best of the bunch!" .)
