Go right inside disreputable bar (5)
I believe the answer is:
drive
'go' is the definition.
(driving is a kind of going)
'right inside disreputable bar' is the wordplay.
'right' becomes 'r' (common abbreviation).
'inside' indicates putting letters inside.
'disreputable bar' becomes 'dive' (**).
'r' inserted into 'dive' is 'DRIVE'.
(Other definitions for drive that I've seen before include "Propel or compel" , "Chauffeur -- force" , "Motivational stuff" , "first shot" , "tenacity" .)
