The oldest operating business in Arizona has nothing to do with the world’s oldest profession. At least, not anymore. Still, a century and a half after opening in 1877, The Palace Restaurant and Saloon is still going strong. The centerpiece of Whiskey Row – a historic district in Prescott, Arizona – The Palace is an easy day trip from Phoenix, Arizona. As its name suggests, Whiskey Row was a saloon-lined thoroughfare, with The Palace being one of about 40 establishments in the strip’s heyday. Wyatt Earp – the legendary lawman, gambler, and outlaw, depending on who you ask – was a frequent patron, along with his brother, Virgil, and his longtime friend, Doc Holliday.
