The Rathskeller at the Montana Club

The Rathskeller is a basement speakeasy-style bar beneath the Montana Club, a private gentlemen's club founded in 1885 and housed in a 1905 clubhouse designed by Cass Gilbert (architect of the U.S. Supreme Court). Its cocktail list revives recipes from Julian Anderson, the club's bartender from 1893 to 1953, reimagined with fresh ingredients. Reopened to the public in 2025 after about a year of renovations under new ownership, it now hosts live music, comedy nights, and a Friday-night Texas Hold'em poker room.

The story

Before you try bluffing your way into Montana's old elite power structure, know that you can walk straight down the basement stairs without showing a membership card. The Montana Club was established in 1885 as a private haven for the state's wealthiest power brokers, housed inside a 1905 clubhouse designed by Cass Gilbert—the same architect responsible for the U.S. Supreme Court building. For more than a century, high-stakes political deals and timber and mining fortunes were negotiated behind those upper-floor doors.

The real soul of the operation, however, sat behind the bar. From 1893 to 1953—a 60-year stretch spanning Prohibition and two world wars—a bartender named Julian Anderson held court beneath the club floorboards. Anderson poured drinks for generations of Helena's political and financial brass, quietly curating a deep library of cocktail recipes that outlasted the Gilded Age that birthed them.

After roughly a year of renovations under new ownership, the building reopened in 2025, officially unlocking the subterranean Rathskeller to the public. The current drink menu resurrects Anderson's original recipes using fresh ingredients, letting you sip authentic 19th-century mixology in the exact basement vault where territory politics were once washed down.

What it's like

Descend below street level off 6th Avenue into a dimly lit subterranean speakeasy that trades upper-crust pretense for stone-and-wood atmosphere. The room shifts tone throughout the week, morphing from low-key early-evening cocktail hour into live music sets, comedy nights, or card playing. If you drop in on a Friday night between 8 PM and 2 AM, you'll find the Teddy Twain Poker Room running Texas Hold'em games with a low-stakes $20 buy-in—just make sure to verify current operating hours before making your trip downtown.

The move: Descend to the basement for Julian Anderson-era cocktails reborn, then stay for a comedy or live-music set.

📍 Before you go Open daily from 3pm (to 10pm Sun-Thu, 11pm Fri-Sat); the Teddy Twain Poker Room runs Fridays 8pm-2am with a $20 buy-in.
