I had the burger here a few years ago an haven't been since. Only thing I could remember was that it was one of the better burgers I had had in a while. I'm trying to recreate it at home. Can anyone post about the details of the ingredients ie toppings, buttered bun or not? I believe there was a giant onion ring on the burger but I could be wrong. Also going with a blend of chuck, brisket and sirloin.
