In a word, KK donuts are "HEAVEN".
THEY ARE NOTHING BUT LARD AND SUGAR. BUT I CAN SAY IT'S THE BEST LARD AND SUGAR I'VE EVER HAD. I EAT THEM WITH TEARS STEAMING DOWN MY FACE, BECAUSE THEY HURT MY TEETH SO BAAAD! BUT I GLADLY SUFFER!!!

BTW, if they're not hot when you buy them, 10-15 seconds in the microwave gets them warm & gooey again!
(They need a "yummy" smiley!)
Good luck, it will be worth the search!
Another Atlanta native here that grew up hoping to see that "Hot Doughnuts" sign in the window at KK. These are the best doughnuts, especially when they are hot.
