Chicago has always had a complicated relationship with its rules. During Prohibition, that relationship was essentially a cold war the city had already decided to lose.
Between 1920 and 1933, while the rest of the country nominally tried to comply with the 18th Amendment’s ban on alcohol, Chicago was running an estimated 10,000 illegal speakeasies. Bootleggers had supply chains. Organized crime had the police and half of city hall in its pocket. And the people of Chicago, by and large, kept drinking.
It’s one of the most genuinely interesting chapters in American urban history, a story about power, money, immigration, corruption, and the limits of telling an entire city what it can and cannot do after dark. And unlike a lot of history, this one has great locations. You can still stand in the rooms where some of it happened.
Here’s what you actually need to know about Chicago’s Prohibition era, and the best ways to experience it tonight.
Why Prohibition Hit Different in Chicago
Most major American cities had their share of Prohibition-era lawbreaking. Chicago turned it into an industry.
The city’s geography helped. Chicago sat at the crossroads of rail lines connecting the entire Midwest, which made it a natural hub for distributing illegal alcohol. Its massive immigrant population — Irish, Italian, Polish, German — had cultural traditions around drinking that Prohibition did nothing to change. And its political machine was thoroughly, almost cheerfully, corrupt.
What emerged was something that looked less like crime and more like a parallel economy. Al Capone’s organization at its peak was generating an estimated $60 million annually (roughly $1 billion in today’s dollars), supplied by breweries and distilleries operating openly in plain sight. Politicians who were supposed to be enforcing Prohibition were attending parties in the speakeasies they were meant to be shutting down.
The Prohibition era in Chicago wasn’t just about booze. It was the moment when organized crime became a permanent feature of the city’s power structure. The gangs that emerged in the 1920s shaped Chicago’s neighborhoods, its politics, and its reputation for decades afterward.
The People Who Defined the Era
Al Capone
No figure is more synonymous with Chicago’s Prohibition era than Alphonse Capone. Born in Brooklyn and transplanted to Chicago in his early twenties, Capone rose through the ranks of Johnny Torrio’s criminal organization before taking over and expanding it into the most powerful crime syndicate in American history. He was known for a cultivated public image, donating to soup kitchens during the Depression, presenting himself as a legitimate businessman, while quietly maintaining operations through violence and bribery. He was convicted of tax evasion in 1931 and died of cardiac arrest in 1947. Chicago has never quite let go of him.
Johnny Torrio
Before Capone, there was Torrio — the organizational mind behind Chicago’s criminal empire. Where Capone was flashy, Torrio was methodical. He built the infrastructure, negotiated the alliances, and essentially created the system that Capone later inherited. After surviving an assassination attempt in 1925, Torrio retired and handed the operation to his protege. His contribution to Chicago’s underworld story is often undersold.
Eliot Ness
The other side of the story. Ness led the Prohibition Bureau’s special team — nicknamed “The Untouchables” for their resistance to bribery — in a series of high-profile raids on Capone’s breweries and distilleries. Their work contributed to the tax evasion case that ultimately brought Capone down. The Untouchables’ story has been told in film and television, but the actual historical record is more complicated and more interesting than most dramatizations suggest.
Where the History Still Lives in Chicago
The good news for history-minded visitors: a lot of Prohibition-era Chicago is still standing. The neighborhoods, the buildings, and in some cases the actual rooms where this history happened are accessible today.
The Green Mill (Uptown)
The Green Mill is the single most significant surviving Prohibition-era venue in Chicago. A jazz club since 1907, it became a Capone favorite during the 1920s. He reportedly had a regular booth and an ownership stake in the operation. The tunnels beneath the club, used to move bootleg liquor and provide escape routes, are part of the building’s legend. The Green Mill still operates as a jazz club today, with much of the original interior intact. It’s one of the few places in Chicago where you can sit in a room that genuinely looks like it did in 1928.
The St. Valentine’s Day Massacre Site (Lincoln Park)
On February 14, 1929, seven men associated with the North Side Gang, led by Bugs Moran, were lined up against the wall of a garage on North Clark Street and shot by gunmen believed to be working for Capone. The massacre effectively ended the North Side Gang as a meaningful rival and cemented Capone’s dominance over Chicago’s criminal landscape. The original building is gone, but the site is marked and remains one of the most visited Prohibition-era locations in the city.
The South Side Neighborhoods
Capone’s operational base was Chicago’s South Side, specifically the Lexington Hotel, which served as his headquarters for much of the late 1920s. The building no longer exists, but the surrounding neighborhood still carries traces of the era. South Side Chicago was where the real organizational machinery of Capone’s empire ran day-to-day, and walking those streets with someone who knows the history is a genuinely different experience from reading about it.
The Craft Distillery Connection
Chicago’s modern craft spirits scene is, in its own way, a direct descendant of the bootlegging tradition that defined the city in the 1920s. Several of the city’s distilleries lean into that lineage with Prohibition-inspired recipes and barrel-aging programs, and visiting one is an easy way to connect the historical thread to something you can actually taste. (You can experience that lineage firsthand on our brewery and distillery tours.)
How to Actually Experience Chicago’s Prohibition History Tonight
Reading about the Prohibition era is one thing. Standing in the rooms where it happened, with someone who can tell you what you’re actually looking at, is something else entirely.
The problem with doing it yourself: Chicago is a big city. The Prohibition history is scattered across multiple neighborhoods. Getting between the Green Mill in Uptown and the South Side in the same evening, without a car, while also actually stopping to take it all in, is a genuine logistical challenge. Most people who try to self-navigate end up at one or two locations before the night falls apart into a standard bar evening.
| Barrel Run Tip: The Barrel Run’s Private Prohibition Tours are built specifically to solve this problem. The Barrel Bus picks your group up, moves you between historically significant stops, and a guide handles the storytelling throughout. You cover more ground, learn more, and drink better than any self-guided version of the same evening. |
Visiting the Sites: What to Know
The main practical challenge with Chicago’s Prohibition history is that it’s scattered. The Green Mill is in Uptown. The massacre site is in Lincoln Park. The South Side is, well, the South Side. These are not walkable from one another, and covering more than one or two in an evening takes some planning.
- Decide your priorities in advance. If you’re exploring independently, pick the one or two sites that matter most to you and plan transportation between them. The Green Mill is the strongest single stop if you only have one evening — it’s a real venue, not a marker or a plaque.
- Check evening schedules. The Green Mill runs live jazz most nights; arriving early gets you a better seat and a better look at the interior. Outdoor sites like the massacre location can be visited any time.
Pair the history with the drinking tradition. Prohibition history pairs naturally with Chicago’s speakeasy-style bars and Chicago’s craft breweries — building your evening around both is how most people end up experiencing the era rather than just reading about it.
Experiencing It With a Group
Prohibition history has a built-in aesthetic — the cocktails, the jazz, the hidden-door mystique — that makes it a popular theme for group evenings: birthdays, bachelorette parties, corporate outings, and out-of-town guests who want something beyond a standard bar night. The storytelling gives the evening structure, and the drinks make it social.
Groups face the same logistics problem outlined above, multiplied by headcount: moving eight people between Uptown and the South Side on a Saturday night is a genuine challenge. Some groups solve it by renting transportation and self-guiding; others prefer to have the route, the storytelling, and the logistics handled for them. If you’d rather have the evening organized for you, you can inquire through our Private Events page and our team will help you build it. Corporate planners can also find format ideas in our guide to entertaining corporate groups near McCormick Place.
Chicago’s History, Still Pouring
Chicago’s Prohibition history isn’t just a footnote in an American history textbook. It’s embedded in the city’s neighborhoods, its architecture, and the way Chicago thinks about itself. The Green Mill is still pouring drinks in the same room Capone drank in. The craft distilleries are carrying the bootleggers’ torch legally. The best way to understand the era is to go see it — and now you know where to look.
