Ive been twice.
Once many many years ago you could actually see the stuff being made *properly* and got loads of chocolate on the way. Also the shop had mishapes which were yum and cheap
Now they are fed to animals iirc.
The second time, many many years later, there was this silly ride which probably is still there and none of the cheapo mishapes - all the pigs (animal not human) had eaten them instead
Cadburys was once a good place to go for cheapo chocolate and a good look round but now due to health and safety $%!#, is nolonger any good.
