I have not ... but if you'll tell me where to exit off of I-20 I will try one the next time we drive through there. There is a little mom & pop donut shop in Monroe, LA that has some really good glazed. Personally, I can't pass up a cinnamon cake.
My BIL says that those things are gonna kill me and I told him that I don't necessarily want to live a few years longer and pass up all of the good food that helps make life worth living. I also remind him that his dad lived to 98 years young and ate any darn thing he desired.
Get off I-20 at Hearne Ave, you can't miss it. If your traveling west take right or left going east
