A man was stabbed to death in front of a Brooklyn fast food restaurant early Wednesday, police said.

The victim was stabbed in the chest and back in front of the Kennedy Fried Chicken next to the Van Siclen Ave. elevated subway stop in Cypress Hills about 12:50 a.m.

Medics rushed him from the scene at Fulton St. and Van Siclen Ave. to Brookdale University Hospital but he could not be saved. He was carrying no identification but is believed to be in his 40s.

The killer got away and is being sought. No weapon was found at the scene.
