It's a case of "you can't have one without the other" (thanks Angelica!), although I don't know about trying these back-to-back! While they're not exactly huge in stature, they certainly make up for it in calories! About 1000 to be exact. Mulligans, the home of the "Ham Dog", also have this beast called "The Luther Burger". The Texas Burger Guy did a write up on it a while ago, here's what he said:
For those that don't know - the Luther Burger is a bacon cheeseburger served on a Krispy Kreme bun. This bad boy is offered up by Mulligan's - a suburban bar in Decatur, Georgia. Click on the picture below to see a really big picture of this mega-artery clogger.
There's also some photos of home made efforts from a Japanese blog, and these guys even tell you how to make your own!! I'm gonna have to try that out I think! :D
