My daughter Edie has restaurants in Wisconsin Rapids and Marshfield. Look for American Table on West Grand in Rapids or Village Garden on Hwy 13 in Marshfield. Good food in both places.
My favorite place in Appleton is the Stone Cellar Brew Bub, excellent food and great beers on tap made in house. It has a very cool atmosphere, as the restaurant/bar is located in the basement of the old brew haus, with authentic stone walls and arched doorways with heavy wood beams. A dimly lit bar area makes it feel almost like a speakeasy. The brewing room is above the restaurant which is clearly visible. The bangers and mash is awesome as well as their scotch egg, definitely worth trying!
MY two favorites in Madison are the weary traveler, and fair oaks diner the first is for excellent beer and dinner fair the latter for a
cozy cheap breakfast nook
