I grew up with KK so I'm amused whenever they move into a new area and everyone goes goofy over them.
They are going no trans-fat...which will probably hurt the taste. Let's face it...that's why comfort food tastes so good...full of sugar, fat, lard and anything else we shouldln't eat.
edited to add:
The reason the "craze" didn't take off in some places wasn't always because people didn't like them. The CEO of KK that tried to take them national and international made a lot of poor business decisions and tried to grow the company too fast. He ended up in trouble because of company book-keeping. A lot of the franchises had to fold because they were counting on revenue as promised by corporate only to find out that the numbers were skewed and profits were not as they thought they would be. Also corporate held the franchisees over the barrel and made them pay exboritant prices for supplies and wares. The CEO has since been replaced and KK is now seeking to have a slower, more controlled growth.
They're still going strong in the South.
