Seek help concerning something on the menu (8)
I believe the answer is:
recourse
'seek help concerning something' is the definition.
I can't judge whether this defines the answer.
'on the menu' is the wordplay.
'on' becomes 're' ('on' can be mean 'with reference to').
'the menu' becomes 'course' (I can't justify this - if you can you should believe this answer much more).
're'+'course'='RECOURSE'
Can you help me to learn more?
(Other definitions for recourse that I've seen before include "Help; option" , "A source of help in a difficult situation" , "Refuge, resort" , "One resorted to" , "Legal right to demand payment" .)
