Set under the dank railway arches, the 90 minute-long production transports spectators through a labyrinth of tunnels with blood-curdling scenes as they go.
Fans of the children’s horror fiction books by American author RL Stein, will recognise scenes from gruesome tales such as Say Cheese, And Die, Stay Out Of The Basement, One Day In Horrorland and Night Of The Living Dummy.
Getting a little Dutch courage, we started our adventure at the Goosebumps bar, where cosmopolitan cocktails come served in giant syringes.
From there the evening began, and a group of us were led by someone wearing a sack over their head through a myriad of corridors, stopping along the way to soak in the action.
The scenes were just the right balance of comedy and creepiness and I will admit to jumping with fright several times.
At one point we were led into an elevator, which then appeared to jam with the lights going out. All of a sudden a trap door in the ceiling then fell open, with a giant furry hand looming down.
Screams pierced the darkness with alarms sounding, before we were eventually let out and escorted to another area.
One woman was so afraid when a trio of men wearing dummy masks appeared that she was on the brink of tears as she ran away, quivering in her husband’s arms.
Luckily we all lived to tell the tale, ending up back at the bar where it all started.
For younger spectators, there is also a children’s version of the production running until June 5.
So if you fancy something a little different to the traditional West End show, get on down to the Vaults now.
