You will have to check out LaCrosse Wisconsin! There is a restaurant called Marge's on Rose (on Rose Street) and they have a HUGE breakfast burrito! There are pictures on the wall of the people that have accomplished it and I know many people have to "train" for it. It is made with about 3 tortilla shells to cover it and it can be cut in half and 2 people normally can't finish it. Defiantly something worth checking out!
They also have the Mess. A huge pile of Ham, Cheese and Hashbrowns that will also qualify you for the wall of fame. Now I'm a pretty big guy and a serious eatter but I can only handle a little over half of it. Fortunately it warms up well the next morning and is still delicious!
I give a big ditto on this one! Unks Mess is nothing to be taken lightly, literaly speaking and figuratively. You wont need another meal for the rest of the day!
