What show should we see in London in December?

[PinkSkiesAtNight]

Hi

I'm meeting a friend in London, late December, who I haven't seen for far too long. We want to go to a show and dinner. I've had a shitter of a couple of years and we would like something fun and fairly easy. Mainstream possibles are Mamma Mia or Mary Poppins. Does anyone have any other suggestions for us? Many thanks!

Jamie, Matilda, Six, Waitress or Mormon

Waitress isn’t re-opening though it’s going on tour and Jamie closes soon.
