Fruit tree is kids' favourite place to visit on high street (except Henry) (8)
I believe the answer is:
sweetsop
'fruit tree' is the definition.
(sweetsop is a kind of fruit tree)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for sweetsop that I've seen before include "West Indian fruit" , "Tropical shrub" , "American shrub" , "fruit tree" , "Custard apple" .)
