Point in shock, impressive food course having no end (9)
I believe the answer is:
epicentre
'point in shock' is the definition.
'impressive food course having no end' is the wordplay.
I cannot quite see how this works, but
'impressive' could be 'epic' (I've seen this before) and 'epic' is present in the answer.
'food' could be 'e' (E is an example) and 'e' is found in the answer.
'course' could be 'n' and 'n' is found within the answer.
This may be the basis of clue (or it may be nonsense).
(Other definitions for epicentre that I've seen before include "Earthquake's point of focus" , "in the middle" , "Area most affected" , "most shocking point" , "hub of quake" .)
