If you want to experience the best brat you've ever had then go out to Headon's in Creston IL (west of Dekalb) and get the Prime Rib Brat. I was first introduced to these on the 4th of July and went out and picked some up for this past holiday weekend. They are simply amazing. The first time I had just the regular prime rib, this time I had the prime rib and mozzarella cheese. They aslo have them with blue cheese, but I don't care for blue cheese so I didn't grab those. The lady there said she makes up a horseradish slurry for them. She said that is great on them, I'm not a fan of horseradish either, but I figured some here may be so I would pass it along. They also have a ton of other brats.
