Often a favourite for swimming bath vending machines, Cadbury's Bar Six was a creamy chocolate bar with a wafer centre and hazelnut cream, they were very similar to a Chunky Kit-Kat. Bar Six had an orange wrapper and was wrapped in a soft foil. This was actually a product of Terry's of York, not Cadbury's. I used to love the plain chocolate ones, and the chocolate pretzels. The Terry's name is now owned abroad and, as far as I know, only Chocolate Orange and Terry's All Gold remain. I may be out of date, but some yeas ago I bought some All Gold and they were horrible (I used to love them when made in York).
