Set of cutlery (7)
I believe the answer is:
canteen
'set of cutlery' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for canteen that I've seen before include "Workers' cafe and cutlery box" , "Water container and works restaurant" , "NAAFI" , "Cafe, flask and cutlery box" , "Workplace eatery" .)
