This is my go-to Culver's whenever I'm driving between Minneapolis and Chicago. It's conveniently located right off of the interstate about 10 minutes north of all the Madison exits. And when you pull up outside you'll immediately notice that the parking lot is packed with cars. This is the sign of a good place!
As for the food, there's really nothing special about it. I like the fact that the burgers are smash grilled and that the buns are buttered. They're not healthy by any stretch of the imagination but if I were forced to pick between McDonald's, Burger King, or Culver's I'm going Culver's.
As for this location, it's clean and well kept and the staff are always friendly. The bathrooms are also clean which is important for the weary traveler.
I can't give this place 5 stars because fast food chains certainly don't warrant that sort of rating but it's quite solid nonetheless. 4 stars.
