Sushi bar beverage (4)
I believe the answer is:
sake
'sushi bar beverage' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for sake that I've seen before include "Benefit - behalf" , "alcoholic drink out East" , "'Reason, purpose (4)'" , "Rice drink - for heaven's ____ !" , "Japanese rice wine" .)
