Stop payment to eat in south end (7)
I believe the answer is:
suspend
'stop payment' is the definition.
'suspend' can be an answer for 'stop' (thesaurus). I am unsure of the 'payment' bit.
'eat in south end' is the wordplay.
'eat' becomes 'usp' (I can't explain this - if you can you should believe this answer much more).
'in' means one lot of letters goes inside another.
'south' becomes 's' (abbreviation).
's'+'end'='send'
'usp' placed into 'send' is 'SUSPEND'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for suspend that I've seen before include "Hang - discontinue" , "Sends up (anag)" , "Stop for a time" , "Interrupt" , "Hang, defer" .)
