Hershey is the only request I get when I visit the UK. I usually pick up a box of them on my way to the airport. I forget the name of the box, something like "Golden Assortment". Also well received are Hershey miniatures. If I was visiting children, I might be looking for full size candy bars. Adults seem to prefer their chocolate one bite at a time; they just keep going back for one more and one more and one more. I prefer Cadbury's. I guess it's all a matter of wanting what you can't have.
