Everything is very well explained by the workers. We learn a lot about trades allowing the construction of the castles of the Middle Ages.
Only downside catering: the quality is there but even going to lunch "late" (1:45 pm) it was 1h tail before reaching the checkout and the choice when arriving was very small. And the prices are also relatively high ( 3.20 for a white cheese, 3.50 for half a drop of fresh organic goat cheese). The best is to bring your own lunch.
