Fire heavily damages Bridget Foy's restaurant on South Street

The fire at Bridget Foy's restaurant on South Street started around 1:30 a.m. Wednesday and was still burning hours later.

The Philadelphia Fire Department says it remains a two-alarm fire, calling for more than 100 firefighters to battle its flames.

The restaurant, located at South Street and 2 nd Street, has been in business for 39 years.

Its flames flooded the neighborhood with heavy, thick smoke at the height of the fire, displacing 11 people from nearby properties.

Fire officials say the fire quickly escalated after crews arrived on scene and a second alarm was sounded just after 2 a.m. Firefighters had to take an exterior attack while fighting the blaze.

According to the fire department, the blaze broke out somewhere on the first floor of the restaurant. Firefighters continue to work to extinguish the fire.

Michael Harris, Executive Director of the South Street Headhouse District, released the following statement Wednesday morning:

"Our hearts go out to John, Bernadette, Bridget, Paul and the entire Foy family.
