Cafeteria (7)
I believe the answer is:
canteen
'cafeteria' is the definition.
(I know that cafeteria can be written as canteen)
This is all the clue.
(Other definitions for canteen that I've seen before include "Snackbar" , "NAAFI" , "Pub in Jo'burg" , "somewhere to eat" , "Soldier's water-flask" .)
