Some menus to peruse in bar (4)
I believe the answer is:
stop
'bar' is the definition.
(bar can mean to stop or prevent)
'some menus to peruse' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'STOP' is hidden in the letters of 'menus to peruse'.
'in' acts as a link.
(Other definitions for stop that I've seen before include "port of call" , "Check" , "Plug; cease" , "as per instruction" , "Come to a halt" .)
