Frequently Asked Questions
What are the minimum spend requirements for wedding receptions at OPSO?
The Larder Room has a minimum spend of £4,000-£5,000 depending on the day, while whole venue hire has a minimum spend of £10,000. The minimum spend includes VAT but excludes the optional 15% service charge.
What are the capacity limits for the different spaces available for weddings?
The Larder Room accommodates up to 44 guests for seated dining or up to 80 guests for standing receptions. For larger weddings, whole venue hire allows you to use both floors with drinks on the ground floor and dinner service utilizing both levels.
What deposit is required to secure a wedding 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 hire of the Larder Room for weddings?
The Larder Room comes with its own dedicated waiting team, a private bar, and the option to play music and add decorations of your choice. The space is exclusively reserved for your event on the lower ground floor.
Can OPSO accommodate 80 guests for a wedding reception within a £4,000 budget?
Based on the venue's minimum spend requirements, a £4,000 budget would only cover the Larder Room (44 seated/80 standing), but this would leave no additional budget for food and beverages beyond the minimum spend. Whole venue hire at £10,000 minimum would be required for optimal service for 80 guests.
What wedding cake options are available and how much do they cost?
OPSO's Pastry Chef can prepare a Valrhona mousse cake priced at £50 per kilogram. This can be arranged as a special addition to your wedding celebration.
Can both the Main Dining Room and Larder Room be used together for larger wedding parties?
Yes, whole venue hire allows you to utilize both floors - guests can start with drinks and canapés on the ground floor Main Dining Room and continue with dinner service using both levels. This option has a £10,000 minimum spend.
What are the service charge arrangements for wedding events?
There is an optional 15% service charge that does not contribute towards the minimum spend requirement. This means it's an additional cost on top of your minimum spend commitment.
Are there any restrictions on music and decorations for wedding celebrations?
The venue allows you to play music and add decorations of your choice in the private spaces. No specific restrictions are mentioned, giving couples flexibility to personalize their wedding celebration.
What is the booking process and can site visits be arranged?
OPSO offers site visits to discuss event details in person before confirming your booking. Contact their reservation desk to arrange a convenient time to view the venue and finalize arrangements for your wedding.
