NORWALK — The owner of Rowayton Seafood Fish Market closed the entire restaurant on Sunday — one day after shutting down the bar area due to a customer testing positive for the coronavirus.

The customer, a man in his 40s, was announced Saturday as Norwalk’s first confirmed coronavirus case. The man was a patron at the Rowayton Seafood’s bar on March 6.

Kevin Conroy, who owns the fish market and restaurant off Rowayton Avenue, said the bartender may have been exposed and has been home for 10 days and has not shown any symptoms of the coronavirus.

“He said he is feeling fine, and is waiting for testing to be certain,” Conroy said Sunday.

No members of his staff have had symptoms of COVID-19, the diseases caused by the coronavirus, Conroy said.

Conroy said staff members who experience symptoms will be required to be tested prior to returning to work.

“We will continue to monitor the situation and follow all CDC guidelines, including sanitizing the entire restaurant as we have been doing,” he said.

After first deciding to keep the restaurant open on Saturday, Conroy said he realized that should also be closed until further notice.

“It is too difficult to manage social distancing in this busy restaurant,” he said.

The restaurant’s fish market will remain open for seafood and to-go orders, Conroy said.

Conroy said the restaurant will remain closed indefinitely.

“We will re-open when it is safe for our customers and staff,” he said.
