Ring lost in bar or beauty parlour (5)
I believe the answer is:
salon
'beauty parlour' is the definition.
(synonyms)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for salon that I've seen before include "Beautician's establishment" , "Call loudly" , "Reception room - social gathering" , "Loans given to hairdressing establishment" , "Hairdresser's premises" .)
