A while back I saw a sign on the Fuddruckers in Addison that they had a huge burger. I do not know if it is a challenge or not you might want to check it out.Are there any restaurants in Chicago with an "finish it in an hour and it's free" eating challenge?
Lavonne's on 95 west heading to Charllotesville has the Big Burger Challege - 5 pound burger and you have to finish it in 35 minutes. Comes with a side of either fries or fried pickles. Good luck, noone has won yet.
