Pub: get value for money? (7)
I believe the answer is:
bargain
'value for money?' is the definition.
(I've seen this before)
'pub get' is the wordplay.
'pub' becomes 'bar' (both are drinking establishments).
'get' becomes 'gain' (gaining is a kind of getting).
'bar'+'gain'='BARGAIN'
(Other definitions for bargain that I've seen before include "Cheap acquisition" , "Barter, negotiate" , "Advantageous purchase" , "Great deal!" , "Count on" .)
