Description: Best toilets for cruising here are on the ground floor, so same level as main entrance off the embankment and west entrance.
If you walk through the west entrance, turn right, you'll see a door in the centre, through which are the toilets. You get plenty of warning here, as there are two doors.
Also, if you walk through the embankment entrance, turn left past the cafe, and you'll see a set of stairs going down. The toilets at the bottom here are good too, as you get a warning, two cubicles here with a small spy hole.
The third good spot is on the basement level below the stage; however, these are often closed.
Please be aware that security is well aware of what goes on and is quite vigilant, so discretion is the word here.
