A famous waterfront hangout in Marin County that boasted plenty of celebrity guests in the 1970s — and where Robin Williams once worked as a busboy — has shut its doors for the second time in 45 years.

The Trident, which spent the 80s, 90s and aughts as Horizons Restaurant, but which reopened as The Trident over a decade ago, has closed its doors, likely for good. As the Chronicle reports, The Trident went out with a New Year's Eve bang, and owner Bob Freeman says that with declining tourist traffic in Sausalito, it was simply time to go.

Freeman was reportedly in talks to sell the restaurant, which fell through, and selling the building is complicated by the fact that its parking lot is owned by the City of Sausalito, to whom any future owner would have to pay rent.

A fine-dining restaurant that took over the Trident's upstairs space in 2023, Ditas, closed its doors last June.

The Trident, which opened as a music venue and bohemian, organic restaurant owned by famed folk group The Kingston Trio in 1966, is legendary for being a hangout of Janis Joplin, Jerry Garcia, Joan Baez, Clint Eastwood, Bill Graham, and The Rolling Stones.

Cocktail legend has it that bartender Bobby Lazoff made a Tequila Sunrise for Keith Richards, and Richards then proceeded to help popularize the drink while the band was touring the country — Lazoff and cowrker Billy Rice can be said to have invented the modern version of the drink, but they took the name from a cocktail actually invented at the Arizona Biltmore hotel in the 1930s, which was made with lime juice and creme de cassis, not OJ and grenadine.

After that came The Eagles' hit "Just Another Tequila Sunrise," and Jose Cuervo started using the recipe to sell more tequila, the drink took its place among the pantheon of 70s party favorites.

The Trident and the Sausalito Historical Society commemorated the (roughly) 50th anniversary of Richards and his first Tequila Sunrise with an event and commemorative plaque dedication at the restaurant in 2023.

Freeman reopened The Trident in 2012, after the original had shut down in 1980, but it never regained any glimmer of its former reputation or prestige. Still, it is one of the first spots drivers see as they drive into Sausalito, and it remained a reliable brunch destination, and continued serving up Tequila Sunrises and Irish Coffees until the end.
