When visiting the Kettle Moraine, the Hamburger Haus is a fantastic place to stop. They are a seasonal little hamburger stand surrounded by picnic tables, with delicious eats for an inexpensive price! Try their flamebroiled burgers, cheese curds, deep-fried asparagus, mac n cheese wedge, and of course their huge servings of ice cream! A great gem off the beaten path and please remember that they only take cash.
