Diners at the Port Chester restaurant Barbeque had to evacuate the premises Sunday after a grease fire broke out in the kitchen.

More than 50 firefighters were on the scene shortly after the flames were sparked. Two families living in apartments above the establishment were evacuated as well.

Officials say the majority of the damage was sustained to the back of the building, including water damage and a collapsed ceiling. Port Chester Fire Chief Charles Nielsen says the damage could have been worse and almost spread.

"The chef tried putting it out, and it extended up into the grease duct and out into the roof," says Nielsen.

The evacuated families have been temporarily displaced. Fire officials expect them to be able to return to their homes later in the week.
