The quantity of chocolate for sale in bulk certainly is surprising. Unfortunately I find American chocolate to be borderline inedible.
There are a lot of great chocolate makers in the US.
Ghirardelli are decent, but I've been relatively hard-pressed to find decent American chocolatiers otherwise. In general, European chocolatiers are in a different league.
I find European chocolate tastes sickeningly sweet, so to each his own.
I don't think it does taste like vomit, but it does smell like it.
Most grocery stores will have a few dozen chocolate bars in their candy aisle that actually say a percentage on them. Not only does this tell you what's not sugared to death, but companies that do this tend to make higher quality chocolate anyways. Anything 70% and higher tends to be tasty.
