Two Quizzes

Would your group find it useful to have a quiz readily available for social and fun occasions, or to avoid having to cancel an event?

Many organisations use a quiz to help people to get to know each other, or to get people working in teams.

The normal "pub" type quiz is useless for more cultural organisations - here may be your answer.

Two quizzes are available,
One concerned with the City of London which is interesting, educational but difficult, and
one concerned more generally with the arts which is far simpler and everyone will get some answers right.

What and where is this?
