Big Time is based at Mill Hill Library - but they are part of the NW7 Hub. You're best to avoid the Tube, as the library is a 30-minute walk away from Mill Hill east underground. While if you catch the overground train to Mill Hill Broadway, the library is just a 5-minute walk away.
There is baby-changing available at the library.
It's easy for buggies and wheelchairs to navigate as the library is just on the ground floor. There are three steps to the entrance, but there is a handrail, plus a ramp.
There are plenty of places to eat in The Broadway nearby. There's a deli, a Pizza Express and a Prezzo, to name just a few.
Tickets are non-refundable. Please print Kidadl booking confirmation and show on entry.
