Here's my gripe with DD: they brew it too dilute. I prefer to take a bag home, grind what I need and drink a more concentrated cup. That way I can have a stronger coffee that tastes good. My gripe with Starbucks is that I've never tasted a blend of theirs that didn't taste like sewage, even if diluted. My second gripe is my wife loves Starbucks. She drinks sewage and loves it! I guess that explains her attraction to me.
I lived in Colombia 3 years and always loved their coffee. I lived in Israel 11 years and lived on imported, powdered Nescafe, which I still like for instant. The national coffee, 'Turkish', is called mud by its fans and the name is right on the mark. As they gentrified, they imported European coffee, which tasted like, guess what- starbuckian sewage! Mud, sewage or instant. Those were the choices. Let me stress, I'm not referring to their own domestic instant which tastes like chalk. Or did. I left 14 years ago. Times change occasionally.

As for the donuts, they are only as good as they are fresh and at most places they aren't very fresh. Krispy Kremes, on the other hand....
