Hidden bars & speakeasies in Boise
Boise hides 6 bars worth the hunt, including Gatsby, Thick as Thieves and Press & Pony. Unmarked doors, back-of-the-laundromat phone booths, no-sign basements — speakeasies that earned the word rather than borrowing it for the decor. They spread across Downtown Boise and Old Boise Historic District, so two or three can make a whole afternoon. Every entry is hand-vetted against real sources — not scraped off a top-ten list or averaged out of crowd ratings.

Gatsby
This is the real-deal password ritual: the code changes every single day and the only way to get it is to call 208-342-4800 the day you plan to go. You walk down Union Alley off 8th Street, find a green light and a wooden skeleton-key sign above a door, knock, and whisper the password to be let into a 1920s-styled library room. Inside it leans hard into Prohibition theater with flapper attire, live music, and cocktails served as prohibition-era "prescriptions."

Thick as Thieves
Entry is a working puzzle: find the side door marked with two thieving birds, climb the stairs, and pick up a vintage rotary phone at the top, then dial 102 to make a mirror-covered door swing open. Behind it is a dark, candle-lit room built for intimate, personalized cocktail service. Open since 2022, its technique-driven craft program earned it a national spotlight as BARTENDER.com's Featured Bar in December 2025.
-
Press & Pony
Opened in 2015 by the founders of Boise Fry Company, this craft cocktail bar shares a doorway and a menu with the burger shop next door. The hidden entrance runs through the restaurant, behind a door labeled as the Boise Fry Company corporate office, though you can also slip in through the bar's own door past heavy burgundy drapery. It sits inside the historic Adelmann Building one block from the State Capitol.
-
8 Horses Lounge
Tucked into the basement of the historic former Boise City National Bank, this lounge keeps the building's banking past visible, including the original 15-ton vault door, a smaller vault, and old signage. The space is arranged like a cozy living room with a hidden wine vault and seating for small groups, built for conversation over wine and craft cocktails. The name nods to the eight horses that hauled the sandstone blocks used to build the five-story facade above.
-
Ampersand
Officially the highest-elevation bar in Idaho, Ampersand is reached by a small ritual: check in at the Art Haus Bar inside KIN and ask for an "elevated cocktail," and staff guide you up to the 14th-floor speakeasy. The intimate room overlooks downtown, the State Capitol, and the foothills. There is no menu at all; every drink is built custom around what each guest wants.
-
Pengilly's Saloon
Housed in the 1892 Spiegel Building, Pengilly's centers on a 100-plus-year-old hardwood Brunswick backbar and a turn-of-the-century National Cash Register, an authentic early-1900s saloon rather than a themed one. It's co-owned by Grammy-nominated jazz singer Curtis Stigers, and the small room regularly hosts live local musicians. Esquire once named it one of the top 100 bars in the nation.
