Well I'm not a drinker and feel paying £3 for a small cup of ice cream is not for me so I stop at a convenience store before entering the theatre, pick up a couple of 500 ml bottles of diet coke cherry (they don't of course sedll that at the theatres and some theatres have the audacity not to sell coke at all but pepsi at inflated prices of course); hopefully the 2 for £1.19 is in effect (still highway robbery for a liter of coke but that's the price you pay for convenience), some chips and an aero mint bar.....

I had a group of high school students on a tour last June and we enjoyed our night at Wicked. We all had on some of our nicer tops; couple girls had on skirts; but all our pants were jeans. We'd been sight-seeing ALL day. And we fit right in. There were all sorts of dress between street casual to not-very-dressed-up office wear. And getting the ice creams and drinks was a real different sweet treat for the kids. You should have a blast!
