For well over two decades, Marie Livingston's Steak House has fed Tallahassee residents its savory cuts of marbled beef, marinated in its signature secret sauce, along with the best Tallahassee seafood. The restaurant, which moved into its third location a few years ago located at Apalachee Parkway, is a raved-about local favorite. The type of restaurant where people plan 11:30 a.m. lunches and 9 p.m. dinners to escape the crowd. But what many Tallahassee residents don't know is that the popular steakhouse isn't an out-of-town chain, nor is the name a marketing gimmick. There is a real Marie Livingston.
