Port served during evening all enjoyed (5)

I believe the answer is:

galle

I'm a little stuck... Click here to teach me more about this clue!

'port' is the definition.
(port in Sri Lanka)

'during evening all enjoyed' is the wordplay.
'GALLE' is hidden in amongst the letters.
However, I'm not sure how the hidden word is indicated.

'served' is the link.

Can you help me to learn more?

(Another definition for galle that I've seen is " Sri Lankan port".)

I've seen this clue in The Guardian.
