Where men might eat pickles (6)
I believe the answer is:
messes
I believe this is a double definition.
'where men might eat' is the first definition.
(soldiers eat in rooms called messes)
'pickles' is the second definition.
('mess' can be a synonym of 'pickle')
(Other definitions for messes that I've seen before include "States of disorderliness and army canteens" , "Military dining rooms" .)
