Food outlet (5,3)
I believe the answer is:
snack bar
'food outlet' is the definition.
(snack bar is a type of food outlet)
This is the entire clue.
(Other definitions for snack bar that I've seen before include "Place serving light meals" , "Small cafe" , "Place serving 17" , "Where one can grab a quick bite" , "Lyons, once?" .)
