The Japanese art and tea ceremony will be wonderful. You can get a small ornamental cup of traditional Japanese tea and then browse around the Japanese pictures.
The traditional tea is an art in itself and so is the pottery it is made from. It is an interesting afternoon because there are demonstrations on how to make traditional tea, which are quite fascinating
There is a real teahouse situated there and a fully guided tour around it. At the end of the tour you can ask any questions that may have arisen in your mind and a qualified guide will be able to give you a detailed answer.
After that you can just sit down and relax in the pleasant atmosphere and just regenerate before you have to get on with your busy life.
Where is all this happening? At The Ashmolean museaum, yes, they have a teahouse there.
