Beside a bar out East (7)
I believe the answer is:
abreast
'beside' is the definition.
(thesaurus)
'a bar out east' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'bar' is an anagram of 'abr'.
'abr'+'east'='ABREAST'
(Other definitions for abreast that I've seen before include "Level in line" , "Side by side; keeping pace" , "Level or keeping pace with" , "Familiar" , "to be up to date" .)
