Bizarre citadel overlooking German city's shops (13)

I believe the answer is:

delicatessens

'shops' is the definition.
(delicatessen is a kind of shop)

'bizarre citadel overlooking german city's' is the wordplay.
'bizarre' indicates anagramming the letters.
'overlooking' means one lot of letters go next to another (down clues only).
'german city's' becomes 'essen's'.
'citadel' is an anagram of 'delicat'.
'delicat'+'essens'='DELICATESSENS'

I've seen this clue in The Telegraph.
