Didn't realise British chocolate was so popular!
I believe that it was Cadbury's chocolates that inspired Roald Dahl's 'Charlie and the Chocolate Factory' - I think Cadbury's used to send chocolate samples to the school and the boys had to review the chocolates.
I'll be bringing a Cadbury's Advent Calender with me during my holiday in December
I think maybe the reason that so many people like the authentic Cadbury's chocolate that you can only get from the UK (probably only England, for that matter - not sure if they have factory's anywhere else in the UK) is because our chocolate (in general) is much creamier and sweeter than chocolate in the US.
However, please remember that there is no England pavilion in EPCOT - it is the UK.
I mean, if you're referring to the country England specifically, great, but if you're talking about the pavilion in EPCOT, it's the UK. Not just England. Please show some respect for us non-English Brits.
There's a Welsh shop and a Scottish shop there, I believe, although I'm not sure how N.Ireland is represented.
