About the Venue

Onyx is a Westlake Village dining venue that works well for private dinners, cocktail-style receptions, client meals, and production use that wants a polished Japanese restaurant backdrop with stronger visual identity than a standard meeting room. The venue is positioned publicly as a distinct function space inside Four Seasons Hotel Westlake Village, which gives it built-in hospitality support while still feeling like its own destination.

Onyx is a private group dining space with a maximum occupancy of 110 guests. The function room includes a sit-down sushi bar, indoor and outdoor terrace seating, and views overlooking the hotel’s signature waterfall. Onyx is also a modern Japanese restaurant with fresh sushi and sashimi, unique cocktails, and sake selection, along with seating at a lively sushi bar and a casual yet refined design. That mix makes the venue attractive for hosted dinners, social events, and content shoots that benefit from a high-end restaurant look without needing a full ballroom.

The venue also benefits from the broader hotel infrastructure. Food and beverage service are clearly supported, seating is built into the venue concept, and the terrace plus waterfall backdrop add scenic value that elevates the event feel. Overall, this is a strong Thousand Oaks area candidate for restaurant-driven events and production use that want Japanese dining, private group flexibility, and a visually distinctive indoor-outdoor setting.
