A bar opposite (7)

I believe the answer is:

counter

This clue is a double definition.

'a bar' is the first definition.
(thesaurus)

'opposite' is the second definition.
(thesaurus)

(Other definitions for counter that I've seen before include "Board game disc" , "Tiddlywink" , "Table for transactions" , "Chip" , "Trounce (anag.)" .)

I've seen this clue in The Independent.
