Um, Denny's is a great big yuck anyway.
I can honestly say I've never drank coffee at a fast food restaurant (except an espresso milkshake once at Burgerville, but that was made from real espresso and real ice cream, not from a machine thing), and the idea doesn't sound appealing. At all.
I'm pretty sure all the McDonald's in our area serve Seattle's Best (they did an advertising blitz a few months back), but if I want a cup of Seattle's Best, I sure as heck wouldn't be trusting the baristas at McDonald's to brew it correctly!

Jack: Tastes pretty good to me.
