Nevada city (4)
I believe the answer is:
reno
'nevada city' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for reno that I've seen before include "Nevadan city" , "City in Nevada noted for quickie divorces" , "Nevada marriage and divorce centre" , "gambling centre" , "City in Nevada known for gambling and easy marriage/divorce" .)
