Try Saracen’s Head to drink and chat (6)
I believe the answer is:
gossip
'chat' is the definition.
(gossip is a kind of chat)
'try saracen's head to drink' is the wordplay.
'try' becomes 'go' (go is a kind of try).
'head to' suggests taking the first letters (I've seen 'heading to' mean this).
'drink' becomes 'sip' (sipping is a kind of drinking).
The first letter of 'saracen' is 's'.
'go'+'s'+'sip'='GOSSIP'
'and' is the link.
(Other definitions for gossip that I've seen before include "Idle, malicious, chatter" , "Natter" , "Casual chatter" , "Casual talk about other people" , "Scandalous rumour" .)
