Bar man leaving The Raven drunk (6)
I believe the answer is:
tavern
'bar' is the definition.
(thesaurus)
'man leaving the raven drunk' is the wordplay.
'man' becomes 'he'.
'leaving' suggests deleting specific letters.
'drunk' indicates an anagram.
'the' with 'he' taken out is 't'.
'raven' with letters rearranged gives 'avern'.
't'+'avern'='TAVERN'
(Other definitions for tavern that I've seen before include "An old inn or public house" , "drinking establishment" , "Old song: 'There is a ...... in the town, in the town'" , "Tap house" , "Building with a bar" .)
