Getting fed up with many aspects of Starbucks just to try to get a cup of black coffee that doesn't taste like dark water.

Anyone know of a reliable place to pop in and get a good to-go cup of strong black coffee without all the hassle? Someone at work mentioned Dunkin Donuts.

I'm in the DFW area, so any ubiquitous chain will work.

Feel like I've turned into that crotchety old fart, .....ing about the customized-orderers, the lazy drive-thru patrons blocking the parking lots, etc.
