Going in for charm (8)
I believe the answer is:
entrance
I believe this clue is a double definition.
'going in' is the first definition.
(I've seen this before)
'charm' is the second definition.
(entrance can mean to charm or bewitch)
'for' acts as a link.
(Other definitions for entrance that I've seen before include "Send" , "lobby?" , "Ingress" , "Vestibule" , "Captivate on way in ?" .)
