The Iceberg Lounge is a trendy Gotham City nightclub, and is the base of operations for the Penguin.
Seemingly tiring of the criminal lifestyle, Penguin will go "legit" and open a posh nightclub, "The Iceberg Lounge". He has three new beauties running his club for him in his absence; Jay, Raven, and Lark. The Iceberg Lounge is the hottest new place in town according to Gotham's jaded in-crowd. The preening Penguin enjoys the good life, but the he hasn't entirely abandoned his criminal ways. Using the club as a front, the Penguin secretly continues to control Gotham City's underworld by bartering in illegal information and stolen goods.
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 tunes.
The Penguin has his own private dining area, upstairs near the bar where he can oversee everything. Some of the nightclub's more secret areas include the Penguin's office and armory, and some of the Iceberg Lounge's hidden back rooms,which serve various criminal purposes.
Batman often infiltrates the Iceberg Lounge to keep an eye on The Penguin's after-hours activities, usually under the guise of Matches Malone.
The DC Universe heavily changed its continuity into the DCnU following the events of Flashpoint in 2011. This was part of an effort to make storylines more accessible to newer readers, beginning with the New 52. This new timeline combines elements from the DCU, Vertigo Universe and Wildstorm Universe while drastically changing the origins and histories of characters.
Penguin reopened the Iceberg Lounge under a new name; the Iceberg Casino. It is now a floating casino and hotel just outside of Gotham, designed like a sparkling iceberg. A secret backroom was the meeting place for some of Gotham's newest villains, such as Hypnotic, Mister Combustible, and Mister Toxic. Not long after its grand opening, the villain Snakeskin attempted to assassinate the Penguin, but was shot before he could succeed.
Rumors began spreading that Lady Shiva was coming to Gotham to kill organized crime. Heeding the warning, Penguin closes down the casino, packing his valuables as he plans to seek shelter somewhere else.
