On the opera house mission, in the basement at the back part of the stage, there is a room that leads to staircases to bathrooms on the first floor. After heading down the stairs there is a room you enter, kill the three rats on the ground and check the bench at the end of the room. There is a keycard for the rat club. Head to the second level where you collect the lightroom keycard. There is a door that cannot be opened. Use the rat club keycard and in there are rats boxing and gambling.
