Private dining area? (4)

I believe the answer is:
mess
'private dining area?' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for mess that I've seen before include "Officers' restaurant - what a dump" , "4 [DISORDER]" , "Where officers eat" , "Mix-up" , "State of confusion and disorderliness" .)
