RUTHERFORD — A 3-alarm fire destroyed a longtime restaurant in the heart of Rutherford's business district Wednesday morning.

Firefighters had to contend with below-freezing temperatures and the collapse of the second floor of 19 Park Ave., home of the Eros Café for more than a decade.

The fire was reported at 2:51 a.m., Rutherford Fire Chief Craig Scott said. It was under control by around 4 a.m.

There were no injuries, he said. The building was gutted. One resident of neighboring 21 Park Av., was displaced due to smoke damage.

A layer of ice covered Park Avenue after the fire, while firefighters huddled in a neighboring business to warm up.

“Weather like this, to have nobody go to the hospital, it’s a good day,” Scott said. “That’s the goal—to keep everybody safe.”

The fire started in the rear of the café, an enclosed patio with tables, Scott said. The Bergen County Prosecutor’s Arson Squad is investigating the cause of the fire, standard practice with overnight fires at commercial buildings.
