The Mark Twain Diner has been serving the public since 1968 and it one of the oldest diners around. The current owners, Frank, Gus and Larry rebuilt the building from the ground up with a complete renovation occurring over the last six months.
With the history of the Mark Twain Diner as basically a landmark in Union, they not only retained the name of Mark Twain with the renovations but presented the history of Mark Twain throughout the diner.
