Since 1892, Diamond Mineral Springs – a venerable family restaurant in Illinois – has been serving its home-style meals to hungry patrons. In fact, its steady stream of loyal customers over the years has made it the oldest continually-operating restaurant in Illinois.

Diamond Mineral Springs began its existence as a health spa in 1870, after a man searching for coal struck a spring of water with a purported “high standard of medicinal properties.”
