Bandits here menaced amateurs playing (9,6)
I believe the answer is:
amusement arcade
'bandits here' is the definition.
(one-armed bandits)
'menaced amateurs playing' is the wordplay.
'playing' indicates an anagram.
'menaced'+'amateurs'='menacedamateurs'
'menacedamateurs' is an anagram of 'AMUSEMENT ARCADE'.
(Other definitions for amusement arcade that I've seen before include "gambling joint" , "Where to find games machines" , "kids might have fun here" , "gambling haunt" .)
