I don't think I ever got around to mentioning the mysterious Frozen Custard ButterBurger Irene & I repeatedly encountered on our Wisconsin travels. It took us quite a while to realize that the Frozen Custard is actually a separate entity from the ButterBurger. Have a look & see if you don't agree that they have a signage problem. I tell ya, we were way more afraid of this thing than of any greasy Chinese buffet. Even after finding out that it's two things, not one.
