"Cheers” setting (3)
I believe the answer is:
bar
'cheers setting' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for bar that I've seen before include "A pub counter, or barristers' profession" , "In Mississippi, measure" , "Prohibit - drinking place" , "Lawyers - for drinks" , "Sandbank; prohibit" .)
