IGNI is a fire-led fine dining restaurant in Mayfair, London. Organisers can book a private dining room for 10 seated guests, or hire the whole restaurant exclusively for up to 34 seated guests. The format suits corporate dinners, client entertaining, product launches, milestone celebrations and intimate wedding receptions.
Seminars and company events
IGNI is a dinner venue rather than a conference space. The restaurant states that its private dining room and its exclusive hire are available for corporate events, work dinners and brand activations. Leadership dinners, client entertaining and team celebrations are the uses it names. The chef's table, served on Thursdays and Fridays for up to 10 guests, is promoted for client entertainment and promotions. There is no plenary room, so plan a meal-based event rather than a full-day seminar.
Weddings and receptions
The official site mentions that exclusive hire suits intimate wedding receptions. The ceiling is 34 seated guests, so this is a format for a small guest list. The team curates the experience personally, with seasonal tasting menus and wine matched to each course. No further wedding details are given, so ask about ceremonies, dates and layouts when you enquire.
Rooms and capacities
The private dining room sits beneath the main restaurant in Mayfair. It seats 10 guests and is available Monday to Saturday, evenings only, for smaller gatherings. Exclusive hire covers the whole restaurant and is available for up to 34 seated guests, depending on the date and the size of the event. Standing capacity is not stated on the official site.
Catering
Catering is in-house. The kitchen is led by Executive Chef Theo Clench and cooks over a four-metre central wood grill. Menus are tasting menus of three, six or nine courses, built on seasonal produce, with seafood at the centre of the offer. Fermentation, preservation and dry ageing are part of the cooking. A sommelier team works with the kitchen to match wines to each course, from whites to richer reds that suit food cooked over open flame. The welcome drink and the final course are part of the planned evening.
History and setting
IGNI presents itself as a restaurant built around the diner's experience. The central grill is the focus of the room, and the cooking draws on coastal traditions. The restaurant is run by Executive Chef Theo Clench and General Manager Gaëlle Dubois, and belongs to the Creative Restaurant Family. A brochure is available from the private hire page.
Getting there
IGNI is at 12 St. George Street, London W1S 2FB, in Mayfair. The site does not name a nearest station. Hanover Square and Oxford Circus are both within walking distance on foot, according to general knowledge of the area, so confirm access with the team.
When you enquire, give the date, the number of guests and the type of event. The form on the private hire page asks for these three items. Availability varies by date and event size, and the team replies to each enquiry. Because the format is a set tasting menu with paired wines, share dietary needs early so the kitchen can plan the courses.
For the smallest groups, compare the private dining room, which seats 10 in the evening from Monday to Saturday, with the chef's table, which runs on Thursdays and Fridays. For anything between 11 and 34 guests, exclusive hire is the option that fits.
