The Big 4 sits on the ground floor of the Huntington Hotel at 1075 California Street, the dark-wood Nob Hill bar and restaurant that reopened in 2026 and walks straight back into San Francisco's railroad-baron past.
The room is named for the "Big Four," the railroad tycoons Collis Huntington, Charles Crocker, Leland Stanford, and Mark Hopkins, whose mansions once crowned this hill. The original opened in 1976, and the revived version keeps the look that made it famous: green leather banquettes, brass, dark paneling, and walls hung with railroad-era prints and memorabilia. It is the rare San Francisco bar that reads as a private club without asking for a membership.
The reopening is the news. The Huntington Hotel went dark for years, and per the San Francisco Chronicle the Big 4 returned to the public in March 2026 under operator Greg Flynn, with live piano back on the schedule Thursday through Saturday. That piano, set against the clubby room, is the whole pitch: this is a bar for a proper drink and a conversation, not a loud night out.
What to order: the room rewards the classics. A well-made Martini or Manhattan suits the setting better than anything trend-driven, and the bar leans into that stirred, spirit-forward register. Sidle up to the bar rather than booking a full table if the plan is drinks, and let the piano carry the evening. Expect Nob Hill hotel-bar pricing, in the upper-end range that the address implies.
Best time to go is Thursday through Saturday evening, when the piano plays and the room is at its best. The kitchen runs a dinner-leaning service, so reservations are the smart call for a table, while the bar itself works for a walk-in nightcap. Early in the week is quieter and more suited to a low-key drink.
Who it is for: cocktail drinkers who want a grown-up room, hotel guests, and anyone marking an occasion with a Martini and a piano. Who should skip it: groups after a casual, loud night, budget drinkers, and anyone looking for craft beer or a sports screen rather than a clubby bar.
The setting carries real weight on Nob Hill. The Huntington Hotel was one of the last grand independents on the hill, and its years dark left a hole that regulars noticed; the Big 4's return, per the San Francisco Chronicle's reporting on operator Greg Flynn, restored one of the city's few rooms built entirely around the railroad-baron era it is named for. The green leather, the dark wood, and the prints are not a theme applied to a new space. They are the look the room has carried since 1976, preserved through the reopening rather than reinvented.
What it offers now is a register the city has lost in most of its newer bars. The piano three nights a week sets a pace that suits a stirred drink and a long conversation, and the bar's posture toward the classics means a Martini or a Manhattan arrives the way the room implies it should. Tripadvisor reviewers welcoming the reopening point to the same thing: the pleasure here is the room and the occasion, the sense of drinking somewhere with a hundred and fifty years of San Francisco money behind the paneling. It is a destination bar for a particular kind of evening, and it knows exactly which one.
Make it the centerpiece of a Nob Hill evening. The California Street room pairs with a cable-car ride up the hill and a nightcap with a view nearby.
