ASBURY PARK -- Two popular restaurants in the city's downtown have closed, officials confirmed.

But why Fish Urban Dining and Cibo e Vino, located on Mattison Avenue just off of Cookman Avenue, abruptly shut down is a mystery.

The owners, James and Karen DeGilio, did not return phone calls seeking comment, and the building's manager, Sackman Enterprises, declined to comment. Facebook pages for both restaurants were deleted.

Asbury Park Deputy Mayor Amy Quinn said she ate at Cibo e Vino on Friday and everything appeared to be fine.

"Cibo and Fish were both restaurants that helped define the downtown," Quinn said. "Great food, fabulous service and a relaxing vibe. We are sorry to see them go."

According to a report from News 12 New Jersey, employees showed up for work on Monday and were told that the two restaurants would be closed for good.

Fish opened in Asbury Park in 2010 and occupied a first-floor space in the historic Post building. A second location opened in the summer of 2015 in Ridgewood. Cibo e Vino, located on the first floor of the old Asbury Park Press building, opened its doors in 2013. Both are owned by the DeGilio's City by the Sea Hospitality Group.

Sylvia Sylvia-Cioffi, executive director of the Asbury Park Chamber of Commerce, said she hadn't heard anything about what may fill the soon-to-be vacant space.

"We have a lot of current vital restaurants and always new restaurants coming to town," she said. "But that doesn't change the sadness we feel from losing Fish and Cibo e Vino."
