The closing of Willie's Duck Diner was only a matter of time due to Moran's now well-established lack of management skills and follow-through.
The reviews of the restaruant on Facebook and Yelp have shown extreme inconsistency, but lousy service seemed to be a recurring theme. That's what you get with a guy like Moran, who touts his "wins", like his appointement to the Mississippi DEC, but more than two years later, still hasn't submitted his bio.
I'm sure that Willie Robertson saw that Moran's management style with the restaurant was damaging his family's name, and so a little over one year after they signed the agreement, and less than 1 year after it opened on Sept 5, 2017, WDD is closed until further notice, probably because Robertson didn't want to renew for another year with Moran and DEWM.
Or maybe it was a health code violation due to the dirty bathrooms (mentioned in several reviews, IIRC).
