Except for soap? (3)

I believe the answer is:

bar

This clue is a double definition.

'except for' is the first definition.
(I've seen this before)

'soap?' is the second definition.
(bar soap is a kind of soap)

(Other definitions for bar that I've seen before include "Prevent; sandbank" , "Counter; pressure unit" , "In Mississippi, measure" , "A pub counter, or barristers' profession" , "Inn" .)

I've seen this clue in the Evening Standard.
