I haven't had it in years, but it doesn't taste like vomit to me. However it is largely flavorless (just sweet) and waxy as fuck. Like it sometimes feels like I'm chewing a chocolate scented candle. Then I can go eat a more expensive bar of dark chocolate and actually get flavor + smooth texture.

The thing is Herseys was made to be a wartime treat. It's made to ration real chocolate. It's not supposed to be fine chocolate. It just became popular because it was cheap and good enough. Plus, I suspect, marketing. I don't know why anyone would buy it other than the price. If you want real chocolate, go for a premium brand or import.
