"The Onion Room was perfect for our needs and just the right size."
- Gabrielle S. Apr 2026
The Onion Room is a private event space in 3 Henrietta Street and is defined by large windows that flood the room with natural light.
Design: The room features deep green-painted walls, a dark wide-plank wooden floor and a decorative fireplace at one end. Picture-rail moulding and linear track lighting maintain a simple, practical interior.
Features: The room includes a long central table and a mix of movable dining chairs and bar stools that can be reconfigured for different layouts. The space provides built-in cupboards and open shelving for staging or storage, and on-site Wi‑Fi for connected events.
Ideal for: Small professional teams and social friend groups benefit from the room's casual layout for seated meals or focused meetings.
What sets it apart: An in-room PA and permission to bring an external DJ allow hosts to create a self-curated sound setup for hosted events.

Clear communication and the service was great. Good location for an intimate baby shower. We had the bottomless brunch option and guests could order the brunch without bottomless too. Our waiter worked so hard and was very attentive.
The poached eggs were a bit cold - but this is only complaint!

I will definitely be hosting my next wine session here. Both the manager and the staff were incredibly professional and maintained such a friendly, welcoming tone throughout. It made a significant difference to our experience, and I look forward to returning soon!
