Goetz told Nashville's News 2 he made the decision to close the 36-year-old business because the landlord decided not to renew their lease.
"He has a right to do whatever he wants and the lease expired after two years," he said. "It is just sad that Hendersonville is going to loose a little piece of history that has been here for a long time."
Many longtime customers stopped by for one final meal on Thursday.
"I hate to see it close. It is a sad day," customer Allan Thomas said.
Customer Valeria Vanderpool added, "I knew it was their last day and I really wanted home cooked food and I was really craving it, so I said I am going to Mallard's. Mallard's is a good idea."
Goetz said he has to be out of his current location by Sunday.
"We've had a lot of crying," he said.
Waitress Shelia Foster added she is not looking forward to trying to find a new job.
"The silver lining I would have out of it is I have met some great people. I have met some great people working here," she said.
Goetz said he hopes to find a suitable new location to reopen the restaurant in the future.
Nashville's News 2 reached out to landlord Harvey Towe in an effort to find out what his plans are for the building, however the calls remained unreturned.
