The Lantern doesn't profess to be anything more than it is. Good American, wisco supper club fare. Prices are very good, and they know how to cook a steak to temperature. Bloody Mary's are great as they allow you to add your own seasonings to taste. Decent wine selection by the glass. They even have sambuca.
Try the surf n turf. Very good at a great price.
Also fried chicken.
Solid choice, and nicest place on lake waubesa.
