Menu suggestion for one preparing to be shot? (3,6)
I believe the answer is:
say cheese
'for one preparing to be shot?' is the definition.
(a photographer may tell someone to 'say cheese')
I can't explain the remainder of the clue.
(Other definitions for say cheese that I've seen before include "Traditional photographer's request" , "Term used by photographer" , "Water feature" , "Photographer's phrase" , "Words required when one is about to be shot!" .)
