Untidy eating place? (4)

I believe the answer is:

mess

This clue is a double definition.

'untidy' is the first definition.
(I've seen this before)

'eating place?' is the second definition.
(I've seen this before)

(Other definitions for mess that I've seen before include "Chaos, confusion" , "difficulty" , "Dirty or untidy state" , "State of confusion and disorderliness" , "Military canteen" .)

I've seen this clue in the Evening Standard.
