Sierra Madre Casino ( hotel ) The Sierra Madre Casino is a location in Sierra Madre in the " " " Dead Money " . Background . < section begin = " background " / > Construction of the Sierra Madre casino began a few years before the Great War . More than just a casino , the Sierra Madre is actually a fortress - a monument to one man ' s inability to let go . Its chief architect and financier , Frederick Sinclair , could see the Great War on the horizon , and wished to protect his love from the coming storm . To that end , he constructed the casino and its outlying Villa , and at the casino ' s heart , he built an almost impregnable vault . The walls of the casino are lined with a metal that interferes with radio reception and broadcasts . What Sinclair did not anticipate was Vera ' s complicity with singer Dean Domino ' s plot to break Sinclair ' s spirit and steal the treasure of the Sierra Madre . Domino had enlisted her aid in his planned heist , later blackmailing her with evidence of her chem addictions , unaware that she was terminally ill . News of this broke Sinclair ' s heart . Left bitter and empty , he transformed his shelter into a trap , ensuring the elevator down to the vault only went in one direction , and upgrading his s to make sure that rescue would never come for Vera and Domino . After Vera broke down and confessed everything , Sinclair , fearing he had overstepped himself , did what he could to reverse his changes , but was limited in success , leaving the casino a deathtrap . He died in the vault , unable to return to the casino . < section end = " background " / > Layout . Cantina Madrid . The Cantina Madrid serves as the casino ' s restaurant and kitchen . The entire area is filled with flammable gas until all the valves in the kitchen are shut off . Dog and God are also inside the Cantina Madrid . Pre - War food ( steaks ) and knives ( cosmic ) are found here , along with alcoholic beverages . Lobby . The lobby acts as a vector for guests to be directed to other localities within the resort . Any other section of the Sierra Madre , except for the vault , can be accessed from the lobby . Casino . The Sierra Madre Casino is simply that : a casino . Fully equipped with Roulette , Blackjack , slots , vending machines , and a bartender , the casino area also does well to showcase the versatility of the properly functioning hologram system installed throughout the resort . The gambling machines can be used by taking to a hologram cashier and trading chips for pre - War money , or pre - War money for chips . Executive Suites . Accessible via an elevator in the lobby , the executive suites are ( or were ) largely what their name suggests : high class bedrooms and suites for the Sierra Madre guests . The area is in a state of noticeably greater disrepair than the rest of the casino , with Cloud seeping in through some of the hallways , many rooms have large holes in the walls , and rubble has blocked many of the hallways , creating a maze . It is largely guarded by . This is where the final confrontation with Christine takes place . Vault . What is labeled as the " " vault " " is actually three areas of what most people would consider " " the basement " " and then the vault itself . Past the winding corridors of the " basement " is the actual vault chamber . From the outside the vault chamber appears to be a stand - alone structure within the Sierra Madre , guarded on all sides with Mk . III . Inside , however , is a vast supply of weapons , medicine and armor . There are a few small pyramid stacks of gold bars , as well as a considerable amount of pre - War money . At the far end of the chamber sits Sinclair ' s terminal , containing a few bitter goodbyes . The room was where Sinclair had hoped that Dean Domino would end up , locking himself inside and passing away within its impenetrable walls . The Tampico . The Tampico was meant to serve the guests of the Sierra Madre as the prime source of entertainment with the best pre - War acts and performers around , including Vera Keyes , Dean Domino , and many other popular entertainers . The Courier ' s final encounter with Dean Domino occurs here during Curtain Call at the Tampico . Appearances . The Sierra Madre Casino appears only in the " " " Dead Money " .
