The Trident and Horizons: Why Sausalito Remembers Both Names
Horizons and the Trident are names from different chapters of the waterfront restaurant at 558 Bridgeway. Horizons followed the original Trident era in 1980, and the Trident name returned in 2012. The upstairs Ondine space had its own identity.
A short timeline of the names
In a San Francisco Bay Times interview, owner Bob Freeman described operating Horizons and later restoring the Trident name. The sequence helps explain why a longtime resident and a first-time visitor may use different names for the same waterfront setting.
- Original Trident era: the restaurant became closely associated with Bay Area music and culture in the 1960s and 1970s.
- 1980: Horizons became the restaurant name.
- 2012: the Trident name was revived.
- End of 2025: the most recent Trident restaurant operation closed.
How to read an old review or photograph
Start with the date, then look for an address and floor. A review of Horizons may help you identify a family photograph or remember a meal, but its menu, opening hours and contact information are not instructions for visiting today.
Room details can help with identification too. A view through the windows, the shape of the woodwork or an exterior sign can connect a remembered meal with a particular floor and period.
If you are putting together a family album, preserve the name that was used at the time. Adding the year and '558 Bridgeway, Sausalito' makes the caption useful even to someone who never knew the restaurant.
Keep the upstairs story separate
The ground-floor Trident/Horizons history is not a complete history of every business in the building. Ondine is associated with the upstairs space, later home to Ditas and then ERIA's event business. For current ERIA directions, the ground floor is identified as 558 Bridgeway and upstairs as 562 Bridgeway.
When arranging a gathering, use the current venue name and the exact floor on invitations. You can include 'the historic Trident building' as a helpful landmark, but it should not replace the address or event entrance instructions.
Common questions
Was Horizons the same location as the Trident?
Yes. In this Sausalito context, Horizons refers to the restaurant chapter at 558 Bridgeway between the original Trident era and the return of the Trident name.
Is the name Horizon or Horizons?
The restaurant is recorded by the Sausalito Historical Society as Horizons. Searching the plural name together with Sausalito and an approximate year helps distinguish it from unrelated businesses.
Does the historic name identify the current operator?
No. A building, a restaurant brand and an event business can have different ownership and operating histories. Use the current booking contact for reservations and event terms.
