The West End of London is well-known for its attractions and hustle and bustle, so that makes it the perfect place to host your meetings and conferences.
The Royal Over-Seas League is our hidden gem, tucked away in the heart of St James and just behind Green Park, with a discreet and serene location you would easily forget that you are in the heart of London!
This central location is perfect as the venue is within easy reach and has great transport links.
The Royal Over-Seas league is one of London’s most unique private members clubs.
This Grade I listed building offers unique conference and banqueting facilities and splendid period function rooms, ideal for holding syndicate workshops and major conferences, to corporate celebrations.
The building is home to seven meeting and function rooms, with the largest accommodating up to 250 guests standing and 196 when seated, whilst smaller spaces seat between 2 and 50 people.

The two largest halls hold up to 250 guests and are ideal for conferences, presentations and small exhibitions. The Princess Alexandra Hall has in-built AV and superb acoustics, whilst the Hall of India and Pakistan can be split into two spaces with a private bar.

If you are on the hunt for a small space to host your board meeting, there are five smaller rooms which can accommodate from 2 to 50 delegates. With elegant period details, these bright and airy rooms can add a touch of history to any meeting or event.
If the Royal Over-Seas League sounds like the venue for you, get in touch with our friendly team to find out more about how we can help you plan your next event.

A night at the Chef`s Table 🍽️
At 10 Union Street, our Head Chef, Jason Bunting, hosted an intimate Chef’s Table, bringing guests to indulge in an evening of dining theatre.
Inspired by his travels through the Subcontinent and South East Asia, each course was packed with bold flavours, stories and a front-row seat to the action.
A brilliant evening shared around the table.
