Being diabetic nowadays, I eat only high-cocoa-content chocolate so Cadbury's Dairy Milk (preferably the 'Whole Nut' variety) is out. I eat Green & Black's 85% Cocoa chocolate now - very dark and bitter, a real acquired taste and very, very more-ish once you've acquired it. Yum!

But I'd defend good old Cadbury's Dairy Milk, the comfort-food of my youth, to the death! :-)
