"The Sopranos" restaurateur (5)
I believe the answer is:
artie
'the sopranos restaurateur' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for artie that I've seen before include "- Shaw, US jazz clarinettist and bandleader" , "Guy" , "Man" , "Shaw, perhaps?" , "-- Shaw, jazz musician" .)
