It appears that Mosun Sushi & Sake/Club M closed last week.
The sushi restaurant and nightclub at 680 S. Coast Hwy. has locked its doors and placed "closed" signs and brown paper over the windows.
Calls to management and the restaurant's general line have not been answered, and the website is no longer working.
A commenter on Yelp reported that the last day of business was Aug. 7 and that employees showed up Aug. 8 to find the establishment boarded up.
