There is a semi-upscale burger joint in downtown LaGrange, IL, Back Alley Burger - www.backalleyburger.com - they also have a location in Elmhurst, IL. One of their specialty burgers is the "Hot-est Insane - est Burger Ever-est.
1/2 lb grass fed beef topped with habanero jam, Trinidad Scorpian sauce, Bhut Jolokia flakes, fried jalapenos, red onion, Thai chili cream cheese on a cayenne spiced Kaiser bun.
I plan to eat one of these next Tuesday night. I will also order one of their chocolate milkshakes in case I need something to tame the heat.
