Something for Caesar from an address in Gaul (8)

I believe the answer is:

dressing

'something for caesar' is the definition.
(as in salad dressing for a Caesar salad)

'from an address in gaul' is the wordplay.
'from' indicates a hidden word.
'DRESSING' can be found hidden inside 'address in gaul'.

(Other definitions for dressing that I've seen before include "Salad sauce; a bandage" , "French or vinaigrette, say" , "Sauce - protection for wound" , "Saucy thing" , "clothing" .)

I've seen this clue in The Guardian.
