Minimum spends vary dramatically based on day, time and venue calibre. China Tang at The Dorchester publishes clear figures: £1,000 for lunch rooms, £2,000-£2,500 for dinner. Mid-week lunches at venues like The Guinea Grill might start around £600, whilst Saturday nights at Novikov can reach £5,000-£6,000 per room. Smaller spaces often work on per-head pricing rather than minimum spends, with three-course menus typically £95-£180 before drinks. The sweet spot? Tuesday to Thursday dinners, when many venues drop their minimums by 30-40%.
For culinary theatre, Murano by Angela Hartnett offers a 12-seat chef's table with panoramic kitchen windows, whilst HIDE's subterranean Reading Room places you steps from the pass. Lucky Cat provides both a 10-seat Chef's Table and an intimate Kitchen Table for 6-12 guests watching the wok action. Alain Ducasse's Table Lumière creates drama differently, with its fibre-optic curtain cocoon, though you're dining in the main restaurant rather than viewing the kitchen. These experiential spaces typically command 20-30% premiums over standard private rooms but deliver unforgettable dinner theatre.
Peak season (September-December) requires 6-8 weeks' notice for premium venues like Claridge's or The Connaught's Mayfair Room, especially for Friday evenings. January-March offers more flexibility, with quality spaces available at 2-3 weeks' notice. Smaller rooms at restaurants like Gymkhana's Vaults or Benares's Sommelier Room can sometimes accommodate last-minute requests midweek. For exclusive venue hire or spaces over 50 guests, start planning 3-4 months ahead. Remember that Mayfair follows the corporate calendar: avoid London Fashion Week, Frieze Art Fair, and major Wimbledon finals unless you're booking months ahead.
At this size, you're in the sweet spot for Mayfair's most atmospheric rooms. Sexy Fish's Coral Room seats 30 at one long table with those famous aquariums as backdrop. HIDE's combined Hide & Seek rooms accommodate exactly 24 with Green Park views. For pure glamour, Bacchanalia's Artemis Room handles 20 beneath maximalist art installations. More traditional options include Scott's 40-seat private room (though you'd only use half) or The Beaumont's Munnings Room. Several hotels offer flexibility at this size: Brown's Roosevelt Room, The Chesterfield's Queen's Suite, or The MAINE's original 1720s Drawing Room all excel at 20-person dinners.
Genuine outdoor private dining remains rare in Mayfair, but several venues blur the boundaries beautifully. The MAINE Mayfair's covered, heated terrace seats 40 privately in Medici Courtyard, functioning year-round. Madison's Manhattan-style terrace offers semi-private areas with St Paul's views, though full exclusivity requires a buyout. The May Fair Hotel's Private Dining Room opens onto an adjoining covered terrace, creating indoor-outdoor flow for up to 62 seated. For summer, Queen of Hoxton's rooftop (technically Shoreditch but worth the journey) transforms seasonally. Most Mayfair venues focus on floor-to-ceiling windows rather than true alfresco dining, given the neighbourhood's formality and weather realities.
Standard inclusions typically cover room hire, dedicated service staff, and basic AV (screen, microphone), though Michelin-starred venues often charge room fees separately. China Tang clearly states 15% service charges apply above minimum spends. Most venues offer tiered menu packages: expect £95-£120 for three courses at hotels like The Chesterfield, rising to £180-£250 at Alain Ducasse or Hakkasan. Wine pairings add £60-£150 per person. Premium venues like Claridge's include dedicated cloakrooms, arrival drinks areas, and concierge services. Always clarify whether quotes include VAT (20%), service (12.5-15%), and any room hire fees, as these can add 40% to your base budget.
Brown's Hotel's Roosevelt Room excels at power breakfasts with abundant natural light and interconnecting options for larger groups. The Connaught's Georgian Room offers refined morning service from 7am, whilst Claridge's Mezzanine rooms provide Art Deco elegance for early starts. The Biltmore's Chairman's Suite suits discreet 14-person breakfast boards, and The Beaumont's Lotos Room handles up to 45 for presentation-breakfast combinations. Most venues offer continental (£35-45pp) or full English (£45-65pp) private breakfast packages. Pro tip: breakfast meetings often waive minimum spends, making luxury venues surprisingly accessible before 10am.
Several Mayfair venues accommodate religious dietary requirements with proper certification. Benares and Gymkhana can arrange halal menus with advance notice, whilst Jamavar works with certified suppliers for both halal and strict vegetarian Jain requirements. For kosher events, hotels like The Dorchester and Claridge's partner with external kosher caterers like Kedassia or Hermolis, though this typically requires 4-6 weeks' notice and adds 30-40% to standard pricing. The Connaught and Brown's Hotel have experience with diplomatic dining requiring specific preparations. Always request certification documentation and discuss kitchen protocols, as some venues cannot guarantee complete separation even with external caterers.
Value in Mayfair is relative, but smart choices exist. The Guinea Grill's upstairs rooms offer proper British dining from £90 per person all-in, remarkable for the postcode. The MAINE Mayfair provides group menus at £100-£150 including generous portions and party atmosphere. Lunch at premium venues offers surprising value: Gymkhana's vaults might waive minimum spends for Tuesday lunch, whilst hotels like The Chesterfield offer three-course lunches from £95. For groups above 30, semi-private areas at Hakkasan's Cellar or Novikov's lounge areas deliver the Mayfair experience without full-room premiums. Book January-March or July-August for potential 20-30% discounts on regular rates.
Gymkhana's two atmospheric Vaults each seat 10 in former bank vaults, creating an intimate speakeasy atmosphere. HIDE's subterranean Broken, Shadow and Reading Rooms (2-8 guests each) nestle in the building's lower ground, though they're designed spaces rather than traditional cellars. The Guinea Grill's Wine Room showcases floor-to-ceiling bottles for 16 diners. For proper cellar dining, Berry Bros. & Rudd in St James's (just outside Mayfair) offers their historic vaulted cellars dating to the 1600s. Most Mayfair 'cellar' spaces are actually sophisticated lower-ground rooms, as genuine Victorian wine cellars rarely meet modern accessibility requirements.
