Krispy Kreme is ok. I prefer Dunkin' Donuts or if you ever make it to the D.C. area, try the Fractured Prune. Words cannot describe the scrumpiousness that is the Fractured Prune.
I love Krispy Creme, but something strange. Our state fair here uses them as a bun for hamburgers. I have never tried it. But they do sell well. They have been doing this around 6 years or so.
