Madison Bistro offers terrific Prix Fixe meals at both lunch (a bargain) and dinner as well. I particularly love the Steak Frite and their Short Ribs. The service is great and the food is always very french and wonderful. The only criticism i have is they don't serve bread plates. Big deal. They do have wonderful wines by the glass and they give you a very nice pour.
This is one of my favorites for lunch, set in an area where there are very few dining options. Be sure to save room for dessert.
