Restaurants want these snails trim, and chef mostly performs (8,5)

'restaurants want these' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'snails trim and chef mostly performs' is the wordplay.
'and' is a charade indicator (letters next to each other).
'mostly' means to remove the last letter (most but not all of the word).
'performs' indicates anagramming the letters.
'chef' with its final letter taken away is 'che'.
'snails'+'trim'='snailstrim'
'snailstrim' put after 'che' is 'chesnailstrim'.
'chesnailstrim' is an anagram of 'MICHELIN STARS'.
