“The proprietor has a hard-earned and enviable academic record in the field of event management, plus a demonstrated flair for the dramatic, all of which points to the organisers knowing both the theory and practice of how to put on a show. Definitely one to watch!”

Chris M. Dickson, Exit Games

You will notice things that you may not have done so before, which makes the experience that bit more interesting.

A fun-filled day out in London that I will definitely take part in again!
