Description
The Iceberg Lounge is a trendy upscale night club located in Gotham City. It is owned by Oswald Cobblepot, aka the Penguin, and serves as his primary base of operations. The two-story, 12,800-square-foot restaurant and lounge included a large pool for pet seals and penguins in the center dining area, an iceberg-like sculpture in the pool, a ship themed dance floor, and polar decor. A tuxedoed jazz band on the sculpture is often seen playing songs. The lounge served as the center of the Penguin's "legitimate" business enterprises.

Gotham
The Iceberg Lounge was originally the Sirens Club, which was owned and operated by Barbara Kean and Tabitha Galavan. After Kean's apparent death at the hands of her former partner, the club was acquired by another ne'er do well, Oswald Cobblepot. The Penguin re-branded the club as the Iceberg Lounge and this became his primary base of operations following his short career as mayor of Gotham City.

The center piece decor of the club was a column if ice, and inside was the frozen form of his Cobblepot's former friend and former deputy mayor, Edward Nygma.
