The best chocolate in the world, in this critic's humble opinion, is made in the United States. And the best chocolate in the United States is made in California, by the Ghirardelli Chocolate Company. It is surely the best chocolate that one can find in so many stores, malls, etc. throughout the United States. Their actual stores are rare, but Kroger, Wal-Mart, Martin's (formerly Ukrops) and a long list of other grocery stores and many malls stock their products.
I have never encountered milk chocolates with caramel filling to surpass the quality of these. These are chocolates deserving of poetry. You can eat them quickly, or take your time and savor every moment of eating every one. The choice is up to you.
