LOUIS COUNTY, Mo. – Shake Shack, a popular fast-casual burger chain, is preparing to open another St. Louis-area location. This time at the site of a former Fuddruckers in St. Louis County.

The second you walk into the last Fuddruckers in California, the cavernous family burger restaurant located inside a nondescript Concord shopping center, nostalgia smacks you in the face.
