Depends. Most coffee I've gotten at McDick's/Starbucks/etc. has been burnt or stale, and that's the what makes it taste like bitter dirt. At that point you need to add stuff to cover it up and make it palatable, which is what they expect you to do and why it's not a problem for them.
But if you get fresh beans, I was surprised to find that you really can taste the difference. Grinding your own beans, you can make an enjoyable cup of black coffee at home with a $20 drip machine, as long as you don't let it sit around for too long.

So coffee DOES taste good, provided you don't fuck it up on purpose.
