At the Cadbury visitor centre, an access fee of $5 per adult (children free) entitles you to view an informative DVD in a theatrette, where you can talk to guides about the chocolate-making process. At the end of the viewing, each person will receive a small gift of chocolates and be invited to relax in the café and browse the great range of gifts, t-shirts, souvenirs and, of course, chocolates. 

The centre is open for half-hour visits from 8.30am to 2.30pm weekdays and bookings are essential (ring 1800 627 367). Cadbury is not open on weekends, public holidays or during factory shutdowns. Factory shutdowns happen around the Easter period and from December to January.
