Fire investigators are trying to determine the cause of the fire that happened at Oak at Fourteenth Restaurant, 1400 Pearl Street, late this morning. Investigators believe the fire started inside the restaurant, then spread to other areas of the two-story building. The fire did not spread to adjacent businesses and no one inside the building was injured.

It happened around 10:34 a.m. Pedestrian traffic was shut down on Pearl Street between 14th and 16th Streets while firefighters were on-scene, and 14th Street between Spruce and Walnut was closed to vehicular traffic. The street is open now.

Damage estimates are not available yet.
