The Prime Quarter is a grill your own steak house with locations in Wisconsin and Central Illinois. It is headquartered in Madison, Wisconsin, and currently has four restaurants in operation. The Prime Quarter Steak House began as a single location in Madison just minutes from the Wisconsin State Capitol. It was a new concept in quality dining because it’s everything a great beef dinner should be. Quality USDA Choice beef, hot out of the oven baked potatoes and a build your own unlimited salad bar with nearly two dozen items! Top that off with family and friends having fun around a live hickory grill, a great price and you’ve got the makings of an exceptional dining value.
