BioShock

In the same area of Fort Frolic, on the first floor, there is a bar at the other end (can't remember what it's called) that is located near the closed-off staircase. If you enter that bar, go around the actual bar area and you will find a door switch just below the countertop. Pressing that switch will unlock another door in that bar, and also open the metal gate and allow you to fully explore that portion of Fort Frolic.

It dosen't i'm stuck on it to and that switch opens a door .

I found out what you have to do.
The bar is called sinclair spirts go there and push the switch behind the bar to open the first door.
Go down the stairs and OPEN the safe (Hack) when you are down there a spider splicker should attack you (the statue standing still) when you kill it return to the stairs with the metal grates if done correctly the sign should be lighting up in neon.
Hope this helps if i dosent ask me.
