Gambling site criminally menaced amateurs (9,6)
I believe the answer is:
amusement arcade
'gambling site' is the definition.
The definition suggests a singular noun which matches the answer.
'criminally menaced amateurs' is the wordplay.
'criminally' indicates an anagram.
'menaced'+'amateurs'='menacedamateurs'
'menacedamateurs' is an anagram of 'AMUSEMENT ARCADE'.
Can you help me to learn more?
(Other definitions for amusement arcade that I've seen before include "gambling haunt" , "gambling joint" , "kids might have fun here" , "Where to find games machines" .)
