There is trouble in Wonderland. And it’s not just that the Knave of Hearts has stolen some tarts nor that the Red Queen appears to be running a police state. The electricity has gone down in the area and the press-night audience for Les Enfants Terribles’ bold – and at times beguiling – take on Lewis Carroll’s glorious creation have been left kettled in a sweaty corridor underneath Waterloo station while increasingly desperate actors improvise.

The show never quite recovered its momentum after the stoppage, but there is plenty to enjoy here, particularly Samuel Wyer’s playful design that leads you on a merry dance through corridors paved with books to a damply delicious encounter with the Walrus. There’s a lifesize Mad Hatter’s tea party and a chance to meet Alice and the White Rabbit along the way. There are times when you feel as if you have dropped down a rabbit hole. You can choose two journeys through the space: eat me or drink me, so if you do go, make sure you split up from friends – one of the pleasures is swapping notes at the end.

The logistics of it, even without the power cut, means that there is quite a lot of queuing or standing around. The sound often lacks crispness and the premise of mutiny in Wonderland isn’t sufficiently developed. At times it seems a little too staid and regimented to be truly nonsensical, and less like a piece of fully fledged theatre than a bespoke journey through the Selfridges’ Christmas window display organised by a canny event management team for jaded customers.

But if you are prepared to overlook the real lack of content or dramatic momentum, there’s pleasure in finding the Wonderland of your imagination recreated before your eyes and, as you step back into the real world, it is with the dazed wonder of awakening from a dream.
