Notable rice dish at party (11)
I believe the answer is:
celebration
'party' is the definition.
(I know that party can be written as celebration)
'notable rice dish' is the wordplay.
'dish' is an anagram indicator (dish can informally mean to destroy).
'notable'+'rice'='notablerice'
'notablerice' with letters rearranged gives 'CELEBRATION'.
'at' is the link.
(Other definitions for celebration that I've seen before include "Party" , "Festival" , "Jollification" , "Revelry" , "The marking of a significant event" .)
