I think most of the normal mass produced chocolate is pretty gross, although I love homemade s'mores.
But both Cadbury, with Green and Blacks, and Hershey, with Dagoba, make good premium chocolate bars.
People who are freaking out make it seem as if you can't buy good American made chocolate anywhere ever at all. You can, but just like here, it costs more.
I think, given the history of the respective companies, it might have been better for Hershey and Cadbury to combine, given the philanthropic nature of the two, but then that is just my opinion.
