Nevada Museum of Art city (4)
I believe the answer is:
reno
'nevada museum of art 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 "gambling centre" , "Nevada gambling resort" , "Nevadan city" , "US gambling resort" , "City in Nevada known for gambling and easy marriage/divorce" .)
