Tony's Chocolonely, based in Amsterdam.

Fazer from Finland. Maybe Panda from Finland, if I want something more eastery, but those are much more sweet and less chocolatey.

Danish Anthon Berg is good and they have some Easter themed chocolates, like chocolate eggs. I also like Fazer from Finland.

I like Lindt, but the increase in cocoa prices have made it difficult to justify spending $5 on a small chocolate bar.

Anything Scandinavian. I spent 2 weeks in Norway when I was in the Navy, and I'll never go back to American chocolate. Flavorless brown wax.

Lindt

People have already mentioned many of the good brands, so I’ll give a shout-out to Björnsted. Especially if you like dark chocolate.

I'm not a big fan of chocolate, they all taste mostly the same to me. So the few times I buy chocolate I go for proximity and pick Valor. Again, no idea if it is good or not.
