Bar drunken tramp pinching pair of spectacles (7)
I believe the answer is:
taproom
'bar' is the definition.
('taproom' can be a synonym of 'bar')
'drunken tramp pinching pair of spectacles' is the wordplay.
'drunken' indicates an anagram.
'pinching' indicates putting letters inside (taking inside).
'pair of spectacles' becomes 'oo' (OO looks like spectacles).
'tramp' anagrammed gives 'taprm'.
'taprm' enclosing 'oo' is 'TAPROOM'.
(Other definitions for taproom that I've seen before include "Type of bar" , "Hotel bar" , "Source of beer" , "Public bar" , "part of pub" .)
