The Edgewater Supper Club at 3522 County Road K in Jefferson, run by Bill and Vicki Millis, looks like any other rural Wisconsin tavern but inside is full of private corners and cozy booths. The menu has a farm-to-table focus. The fireplace has an inscription from the 1930s above the hearth, and the river view room lets diners watch leaping fish and hummingbirds.
