The Interval at Long Now

The Interval at Long Now isn’t your typical bar—it’s a cultural hub, cocktail lounge, and intellectual playground nestled within Fort Mason Center in San Francisco. Created by The Long Now Foundation, this venue is designed as a salon and museum for long-term thinking, where patrons can sip finely crafted drinks surrounded by mechanical prototypes of 10,000-year clocks, rare books on science and history, and immersive art installations. The bar’s design is stunning—industrial yet warm—with floor-to-ceiling bookshelves, brass fixtures, and a two-story “Library of the Long Now.” It's as much a space for contemplation as it is for conversation. Guests can enjoy unique cocktails inspired by science and history, from the “Martian Tea” to the “Manhattan Project,” all created with precision and care. More than just a bar, The Interval hosts public talks, salons, and showcases ideas that span centuries. It’s a meeting ground for futurists, artists, scientists, and curious minds from all over the world. Whether you're here to drink, read, or just reflect on humanity’s long arc, this is one of San Francisco’s most thought-provoking hidden gems.
