The Mob Museum is giving downtown Las Vegas a Halloween plan that does not require a nightclub table or a haunted-house ticket. On Saturday, October 31, the museum is splitting the party between Starlight Plaza and The Underground speakeasy.
The outdoor portion runs from 7 p.m. to midnight at Starlight Plaza. The Underground starts at 8 p.m. and continues until midnight, with live jazz, close-up magic and cocktails in the museum’s Prohibition-era setting. Admission to the Halloween party is free; The Underground is 21+.
The password
If you are heading downstairs, remember “SPELLS & SPIRITS.” It is the night’s speakeasy password and exactly the kind of small detail that makes this feel more considered than a generic costume party.
