Keep coming over chilled at Iceland stores (7)
I believe the answer is:
citadel
'keep' is the definition.
(thesaurus)
'coming over chilled at iceland stores' is the wordplay.
'coming over' says the letters should be written backwards.
'stores' indicates a hidden word.
'ledatic' can be found hidden inside 'chilled at iceland'.
'ledatic' reversed gives 'CITADEL'.
(Other definitions for citadel that I've seen before include "Structure in place to protect" , "Highly-secure building" , "Fortress overlooking a city" , "Stronghold (of the Salvation Army?)" , "where Salvationists meet" .)
