(Fond du Lac) An iconic restaurant in Fond du Lac is closing its doors after more than 80 years in business. Travelers familiar with Schreiner’s would make a point of stopping there for a meal. Schreiner’s opened its doors in 1938 as “The Grill.” It’s had several location changes over the years moving to its current location at the intersection of Interstate 41 and Highway 23 in 1971. Recent years have seen the restaurant cut back to offering only breakfast and lunch, with Safer at Home restrictions reducing it to only offering curbside take-out one day a week. An official timeline for its closing has not been announced.
