I believe the answer is:

feast

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

'entertainment' is the definition.
(I've seen this before)

'noisy oriental' is the wordplay.
'noisy' becomes 'f'.
'oriental' becomes 'east' (I can't explain this - if you can you should believe this answer much more).
'f'+'east'='FEAST'

Can you help me to learn more?

(Other definitions for feast that I've seen before include "Banquet or religious festival" , "Abundant meal" , "Celebratory meal" , "Lavish meal" , "Repast" .)

I've seen this clue in The Globe and Mail.
