The Interval at Long Now

A bar, cafe, museum, and
the home of The Long Now Foundation

Come enjoy coffee or cocktails surrounded by books floor-to-ceiling and mechanical wonders from a clock engineered to last 10,000 years. Featuring Brian Eno's music and his ambient painting—a continuously evolving, never-repeating work of art. An inspiring venue for great conversations and delicious drinks.

Located in San Francisco's historic Fort Mason Center within sight of the Golden Gate Bridge and Alcatraz.

Award-winning bartender Jennifer Colliau has designed an extensive time-inspired drink menu that includes some of the earliest cocktails ever made, drinks from around the world, and time-shifted concoctions that take hours to make but are ready whenever you arrive.

We also serve mixological-quality low- and no-alcohol drinks made with fresh ingredients, as well as fine tea and coffee.

The Interval pairs well with all the attractions of Fort Mason Center including legendary vegetarian restaurant Greens right next door.

Join the The Interval Crowdfund

More than one-thousand donors have given to our 'brickstarter' fund. We continue to accept tax-deductible donations to help fund finishing touches on The Interval including acquiring all the books for the Manual for Civilization collection (an ongoing effort).

Donations are tax-deductible and we have many gifts to thank you for your generosity including Challenge Coins, Long Now flasks, and bottles of limited edition whiskey and gin created just for us by St George Spirits. Donors also enjoy early notice about our events.
