During Prohibition, illegal drinking spots in the United States were known by many names: speakeasies, blind pigs, blind tigers, private salons and hidden bars.
The word “speakeasy” is often linked to the idea that customers had to “speak easy” or speak quietly when asking for alcohol, so police or neighbors would not hear. Today, Las Vegas has many modern speakeasy-style bars, but few connect the theme to real history as directly as The Underground at The Mob Museum.
The Underground is a Prohibition-era speakeasy and distillery located in the basement of The Mob Museum in Downtown Las Vegas. It has a hidden side entrance, a weekly password, craft cocktails, shareable bites, live music and exhibits about the Roaring Twenties, Prohibition and the Mob’s role in illegal alcohol.
Here is the updated guide to The Mob Museum Speakeasy, including hours, tickets, parking, password, entrance, menu and museum experiences.

The Underground is located in the basement of The Mob Museum and is included with museum general admission. If you are only visiting the speakeasy, you can get the weekly password, find the side door and enter without buying a full museum ticket. Speakeasy access is restricted to guests 21 and older. :contentReference[oaicite:2]{index=2}
Online reservations are strongly encouraged for museum tickets because they may offer online-only discounts and help ensure availability. Ticket prices can change, and interactive experiences may cost extra, so check the official ticket page for the current General Admission, Deluxe and Premier options before buying. :contentReference[oaicite:3]{index=3}
The older COVID-era wording about masks and sanitizing should be removed. Visitors should follow any current health, security or bag rules posted by the museum, but the article should not present old pandemic entry rules as current.
Transport and Parking
Getting to The Mob Museum is easy from most Downtown Las Vegas hotels and attractions.
Limited parking is available in the lot next to The Mob Museum. Current official parking information lists the museum lot at $8 for four hours. If the lot is full, additional paid parking is usually available within walking distance at nearby downtown casinos such as Downtown Grand, Main Street Station and El Cortez. :contentReference[oaicite:4]{index=4}
The free Downtown Loop is also useful for reaching The Mob Museum. The city shuttle serves major downtown stops, and The Mob Museum is one of the listed Downtown Loop locations. :contentReference[oaicite:5]{index=5}
If you are coming from the Strip, the RTC Deuce is the easiest public bus option. The Mob Museum’s transportation page describes the Deuce as a double-decker bus running from the Strip to Downtown Las Vegas, with frequent 24-hour service. Traffic and construction on Las Vegas Boulevard can affect travel time, so leave extra time if you are going for a timed museum ticket or event. :contentReference[oaicite:6]{index=6}
How Did Speakeasies Come To Be?
Speakeasies became famous during Prohibition, when the United States banned the manufacture, sale and transportation of alcoholic beverages from 1920 to 1933.
Instead of eliminating drinking, Prohibition helped push alcohol underground. Hidden bars, illegal distilleries, bootlegging networks and rum-running operations grew across the country. Organized crime groups found an enormous opportunity in supplying illegal alcohol to people who still wanted to drink.
The Underground at The Mob Museum recreates that Prohibition-era atmosphere in a legal, museum-connected setting. Exhibits, videos and artifacts in the speakeasy tell stories from the Roaring Twenties, including flappers, jazz, Prohibition, bootleggers and the rise of the Mob. :contentReference[oaicite:7]{index=7}
The result is more than a themed bar. It is part cocktail lounge, part museum exhibit and part history lesson.

The Entrance to The Underground Speakeasy
The fun of The Underground starts before you even order a drink.
There are two ways to enter:
Entry From Inside The Museum
If you buy museum admission, you can access The Underground from inside the museum. Head toward the basement level, where you will find the Prohibition exhibit area, distillery and speakeasy.
This is the best option if you want to see the full museum first, then end your visit with a cocktail.
Entry From The Outside Side Door
If you only want to visit the speakeasy, use the hidden side entrance.
The official page says that guests who are just visiting the speakeasy should get the password, find the side door and enter. The outside entrance keeps the speakeasy feeling more authentic, because it recreates the hidden-entry ritual of Prohibition-era bars. :contentReference[oaicite:8]{index=8}
Look for the barrel and stairway near the side of the museum. Knock, give the password when asked, and enter if space is available.
Since The Underground can close early for private events, always check the official early-closure notice before planning your visit.
Where Is the Password to The Speakeasy?
The Underground uses a weekly password.
The official speakeasy page currently displays the weekly password directly on the website. The password may also be shared through The Underground’s social media, especially Instagram. :contentReference[oaicite:9]{index=9}
If you do not have the password, staff may still help you, but having it makes the experience more fun and keeps the hidden-bar theme intact.
Before you go:
- Check the official speakeasy page for the current weekly password.
- Check Instagram if you want event updates or live-music reminders.
- Confirm there are no early closures or private events.
- Bring valid photo ID because The Underground is 21+.
What to Order at The Underground
The Underground serves Prohibition-era craft cocktails and shareable bites. The official page describes the menu as authentic, Prohibition-era craft cocktails and shareable bites, and the speakeasy also hosts live music and private events. :contentReference[oaicite:10]{index=10}
Classic-style drinks and signature cocktails may include names such as Bee’s Knees, Moonshine Mayhem and other Prohibition-inspired drinks. The Underground is also connected to the museum’s on-site distillery, where Mob Museum Moonshine is produced and featured in some cocktails.
The menu can change, and The Underground introduced a refreshed history-inspired menu in 2026. Signature drinks such as Giggle Water, Bee’s Knees and the Underground Old Fashioned have remained part of the conversation around the menu, while new cocktails and shareable bites may rotate. :contentReference[oaicite:11]{index=11}
If you are visiting mainly for drinks, go directly to The Underground. If you want the full history experience, visit the museum first, then finish with a cocktail in the speakeasy.
Brief Overview of the Museum
The Mob Museum is housed in a historic former U.S. Post Office and Courthouse in Downtown Las Vegas. The building opened in the early 1930s and later became one of the most important historic buildings connected to Las Vegas crime and law-enforcement history.
One of the museum’s most significant spaces is the restored courtroom tied to the Kefauver Committee hearings. Those hearings investigated organized crime across the United States and helped expose the national reach of the Mob.
The museum now explores organized crime from multiple angles: mobsters, law enforcement, Prohibition, gambling, rackets, wiretapping, forensic investigation, courtroom history and modern organized crime.
The Underground fits naturally into that story because Prohibition was one of the major forces that helped organized crime expand in the United States.
Interactive Experiences
The Mob Museum also offers interactive experiences that can be added to a visit.
- Crime Lab: A mediated forensic science experience covering fingerprint analysis, DNA profiling, evidence work and medical-examiner-style investigation.

Current official hours are Monday-Thursday 11:30am-7:30pm, starting every hour on the bottom of the hour, and Friday-Sunday 11:45am-7:15pm, starting every 45 minutes. Participants must be at least 13, and only guests 21+ with valid ID can take part in the sampling portion. :contentReference[oaicite:13]{index=13}
- Firearm Training Simulator: A law-enforcement-style video and role-playing simulation. Current official hours are Monday-Thursday 10:30am-5:45pm and Friday-Sunday 10am-8pm, starting every 15 minutes. Participants must be at least 16, and guests under 18 must be accompanied by a responsible adult. :contentReference[oaicite:14]{index=14}
