Exclude from the pub (3)

I believe the answer is:

bar

I believe this is a double definition.

'exclude from' is the first definition.
(thesaurus)

'the pub' is the second definition.
(I've seen this before)

(Other definitions for bar that I've seen before include "Rigid rod" , "Drinking place - lawyers!" , "Barristers - band" , "Sandbank; pub counter" , "sovereign" .)

I've seen this clue in The Mirror and the Evening Standard.
