gastronomic

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

'dining' is the definition.
(thesaurus)

'front of gut enormous' is the wordplay.
'front of' indicates taking the first letters.
'enormous' becomes 'astronomic' (I've seen this in another clue).
The first letter of 'gut' is 'g'.
'g'+'astronomic'='GASTRONOMIC'

'all to do with fine' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.

Can you help me to learn more?
