A restaurant manager was shot dead in front of his workplace in Queens, law enforcement sources said yesterday.

Neville Brown, 56, was chatting with a female friend while seated in a parked car about 10:30 p.m. Friday when a gunman dressed all in black walked up, shot him several times in the back of the head and fled without saying a word, sources said.

Brown was a manager at the Cozy Corner Jamaican Restaurant on 243rd Street in Rosedale. His criminal record includes an arrest for selling marijuana in the 1990s, records show.
