As for Starbucks, the magazine called it “strong, but burnt and bitter enough to make your eyes water instead of open.”
This is no surprise to me. I've always hated the burnt smell and bitter taste of Starbucks' regular coffee. It's gross.
I don't think people who go to Starbucks drink the regular coffee anyway. From my observations they always get the expensively sweet vanilla-caramel-frothy drinks.
Dunkin Donuts makes the best regular coffee.
McDonald's coffee will give you third degree burns.
