'not irremediably wild' is the definition.
I can't judge whether this defines the answer.

'diners admitting graduate' is the wordplay.
'diners' becomes 'table' (I can't explain this - if you can you should give a lot more credence to this answer).
'admitting' means one lot of letters goes inside another (admit can mean to welcome in or accept).
'graduate' becomes 'MA' (abbreviation for Master of Arts).
'table' placed around 'ma' is 'TAMABLE'.

'is' is the link.

Can you help me to learn more?
