I think the only place I frequent that always has a consistantly good cup of coffee is Waffle House. http://www.wafflehouse.com/coffeestory.asp

At home I brew the same stuff I grew up on, Folgers Classic Roast.

Starbucks' popularity can't be denied, but their swill always reminds me of some coffee I had in Central America once, it was ladled out of a big cook pot with about a quarter inch of burned coffee residue in the bottom.
