Caligula's Palace

In the video game, Grand Theft Auto: San Andreas, Caligula's Palace is co-owned by the Leone Mafia Family, the Sindacco Mafia, and the Forelli Mafia and consists of blackjack, roulette, poker, slot machines, and a hotel suite that leads to the rooftop. There is also a basement area that comes in handy during one of the Las Venturas missions. Ken Rosenberg assigns all the Mafia missions, including the one where the player has to fly to Liberty City to fight inside Marco's Bistro. After the Ocean's 13 esque heist on the casino, the Leone's abandon the establishment. Which leads some to presume that the Sindaccos move back into the Casino.

Caligula's Palace is based on real Las Vegas casino Caesar's Palace.
