Good Evening Mr. Tudor
If you get a chance, try the Amedei single estate chocolates.
Amedei chocolates may be made in Italy, but they buy beans from single estates in sundry countries in South America & the Caribbean.
For a less austere taste, the Swiss are by far the best; I am particularly fond of the truffles from Hefti in Zurich, but they are never exported as they have to be eaten within 48 hours of being made. If I am travelling, then I bring Sprungli's truffles, which are almost as good.
In Belgian chocolate, avoid the big names & try Wittamer in Brussels, but the rules about Hefti apply there also.
But sometimes you just want to have a Marcel Proust
Madelaine moment and relive your childhood & then, nothing but Cadbury's Fruit & Nut will do.
Good Night
