Having grown up in Green Bay, perhaps we see the Kroll's hamburger a bit differently from others. It's a legend across the street from our football legends. It's a casual place, nothing fancy. While I usually ask them to hold the butter, others say bring it on! It's our go to place before the big game; things are hectic at that time, but we are used to it. There is a burger somewhat close in taste to Kroll's up in Fish Creek (Door County) called Not Licked Yet. I say if you're in the area, give 'em a try!
