Hearty piece of steak and drinks (8)
I believe the answer is:
'drinks' is the definition.
(cordial is a kind of drink)
'hearty piece of steak' is the wordplay.
'hearty' becomes 'cordial' (synonyms).
'piece of' indicates taking the first letters.
The initial letter of 'steak' is 's'.
'and' is the link.
