Place to eat hash? (4)
I believe the answer is:
mess
I believe this clue is a double definition.
'place to eat' is the first definition.
(I've seen this before)
'hash?' is the second definition.
(making a hash of something is making a mess of it)
(Other definitions for mess that I've seen before include "Officers' restaurant - what a dump" , "Medley" , "Where officers eat" , "stew or > jam" , "State of confusion - where servicemen eat" .)
