Big Sal's office is located upstairs from the main casino floor of Gomorrah, next to the Zoara Club. In order to reach this area, the Courier must first go through Brimstone. Next to the bar are two red couches, and a stairway leading upstairs. After reaching the pool tables, open the door on the far right side of the room. A Lockpick skill of 100 is needed.
The door to open the office is classified as owned, but picking the lock will not result in loss of Karma. The Troike blackmail note is located inside the room's safe by the wall. There is no loss of Karma for opening the safe and taking the note. A Lockpick skill of 75 or higher or a Science skill of 50 or higher is required to open the safe.
