If Hershey's is America's best attempt at chocolate, I'm glad I'm English.
For chocolate, it's Snickers, Twix, Lion Bars, Picknics (basically a Lion Bar with rasins), or Kit-Kats (worlds most popular biscuit, invented by a nation of tea drinkers

).
My favourite sweet is probably plain, uncoated Kendle mint cake, but it's probably not wise to eat it at night in October if you like your mouth.
In England, we've got Mountain Dew back (you call this an energy drink now?) and we've started getting Lucky Charms again in super markets, but still no god damned Jolly Ranchers, and I'm not importing them at nearly £5 a bag >:[
