The reputedly "haunted" Excalibur building was designed in 1892 by famed architect Henry Ives Cobb, and has been honored with a Historic Landmark designation. Located in Chicago's River North entertainment district across from the Hard Rock Cafe, this unmistakable red granite castle is a Chicago nightlife icon that boasts Chicago's largest dance floor, multiple lounges, billiard tables, late-night dining, and live entertainment.
