Put down hospital food (4)
I believe the answer is:
dish
'food' is the definition.
(dish is a kind of food)
'put down hospital' is the wordplay.
'put down' becomes 'dis' (I've seen this in another clue).
'hospital' becomes 'H' (abbreviation for hospital on maps).
'dis'+'h'='DISH'
(Other definitions for dish that I've seen before include "course" , "Food container; aerial" , "(Food for) serving plate" , "Kitchen container" , "Sky can be seen through this" .)
