The Underground at The Mob Museum

Overview

Hidden in the basement of The Mob Museum in downtown Las Vegas, The Underground is an immersive Prohibition-era speakeasy and working distillery that transports visitors back to the 1920s. The space is filled with authentic artifacts from the bootlegging era, creating an atmosphere that feels genuinely historic rather than themed. A copper still produces house-distilled moonshine on-site, and the bartenders craft cocktails using recipes and techniques from the Prohibition period.

Entry requires a password, which adds to the clandestine thrill — you can typically find it on The Mob Museum’s social media channels or website. Once inside, the dimly lit space with exposed brick walls and vintage furnishings makes you feel like you’ve stepped through a time portal. The speakeasy regularly hosts live jazz and blues performances, completing the 1920s atmosphere.

Unlike many ‘speakeasy-style’ bars that merely borrow the aesthetic, The Underground is housed in a real piece of history — the building itself was the site of one of the most significant events in organized crime history. It’s equal parts bar, museum, and experience.
