A couple of shots with the contrast pushed a little to far and a real grainy look would help enhance that gritty, surreal feel of the place. Try some real high ISO's with exposer compensation in the negitives may get you some real grainy B&W's... some may not like that type of picture, but in this case I think that is what would give the right feel to the picure.

It also may help the effect to push the sharpening a little farther than you would normally.
