Redline Sports Grill and RPM Nightclub on North Oracle and West Wetmore roads reportedly has closed.

The restaurant and sports bar, owned by Luke Cusack, apparently closed early last week. The business phone has been disconnected and its Facebook page eliminated.

  The restaurant was opened in early 2011 by Cusack and partners, who initially included Fourth Avenue burger baron Lindy Reilly. Reilly pulled out of the restaurant last spring and threatened to sue Cusack to retain the intellectual property of his food. Reilly wanted to make sure his wild burger combinations first made popular at his namesake Lindy's on 4th restaurant were taken off Redline's menu.
