She's cooked in shopping centre dining room (4,4)

I believe the answer is:

mess hall

'dining room' is the definition.
(mess hall is a kind of dining room)

'she's cooked in shopping centre' is the wordplay.
'cooked' indicates an anagram.
'in' is an insertion indicator.
'shopping centre' becomes 'mall' (a mall is a large shopping complex).
'shes' with letters rearranged gives 'essh'.
'essh' inserted into 'mall' is 'MESS HALL'.

(Another definition for mess hall that I've seen is " where soldiers eat".)

I've seen this clue in the Sydney Morning Herald.
