Frequently asked questions
What are the capacity limits and minimum spend requirements for private events?
The Larder room (lower ground floor) accommodates up to 44 guests for seated dining and up to 80 guests for standing receptions, with a £4,000-£5,000 minimum spend depending on the day. For exclusive hire of the entire venue, the minimum spend is £10,000, allowing use of both floors for larger events starting with drinks on the ground floor.
What deposit is required to secure a booking and how does it work?
A £2,000 deposit is required to confirm your reservation. This deposit will be refunded following the event, making it essentially a security deposit rather than a payment towards your final bill.
What's included with the private event package?
Private events include exclusive use of the Larder room with its own dedicated waiting team, private bar, and the option to play music and add decorations of your choice. The space comes fully equipped for your event without additional hire fees for these basic amenities.
Are there additional service charges beyond the minimum spend?
Yes, there is a discretionary 15% service charge that applies to your final bill. This service charge does not count towards meeting your minimum spend requirement, so it's an additional cost on top of the £4,000-£5,000 minimum.
Can I bring my own decorations and play music during the event?
Yes, you can add decorations of your choice and play music during your private event. The venue allows customization to suit your event's theme and atmosphere, and music options are included as part of the private event package.
What catering options are available and can I order custom items?
The venue offers sample menu options detailed in their Event Brochure with modern Greek cuisine. Additionally, their Pastry Chef can prepare custom Valrhona mousse cakes at £50 per kilo for special occasions like birthdays or celebrations.
How far in advance can I book and what's the booking process?
You can book events well in advance - quotes show bookings being taken for dates over a year ahead (October 2026). The process involves initial availability confirmation, receiving the Event Brochure with menu options, and scheduling a venue visit to discuss event details before finalizing.
Is there flexibility in pricing for different budgets?
The venue operates on fixed minimum spend requirements rather than flexible pricing. However, quotes show some events receiving discounts through Hire Space, and the venue appears willing to work within stated budgets when they align with minimum spend requirements.
What are the typical event timings and duration limits?
Events typically run in the evening with common start times around 6:00-8:00 PM. The venue can accommodate events until late night (quotes show events running until 11:00 PM to 1:00 AM), making it suitable for dinner parties that extend into evening celebrations.
Can the venue accommodate both cocktail receptions and seated dinners?
Yes, the Larder room is designed for both formats - it seats up to 44 guests for formal dining or accommodates up to 80 guests for standing cocktail receptions. The space includes a private bar making it ideal for events that combine both reception and dining elements.
