Waterfront birthday venue, Sausalito
If the point of the birthday is to be outside by the water, the Ground Floor is the room to look at. ERIA Sausalito Ground Floor, at 558 Bridgeway, is a 5,100 sq ft historic space with a waterfront deck of more than 2,000 sq ft.
The deck faces San Francisco Bay, so guests can step outside with a drink and look at the hillside across the water.

The deck is the main attraction
The deck is large enough to be a party area in its own right and not a spot for a few people to squeeze onto. There is also 600 sq ft of covered seating, which keeps part of the outdoor space usable if the weather shifts.
Inside, a former Trident space
The room keeps its original Art Deco character from its days as the historic Trident. A fully equipped bar sits in the space, and the floor is step-free, which matters for older relatives and anyone with a stroller or mobility aid.
Standing or seated
The Ground Floor holds 500 standing or 300 seated. A relaxed afternoon birthday with drinks on the deck suits the larger standing number; a long lunch or dinner leans on the seated count.
