"Minimum Spend: Varies on the day, time, and season The private dining options at Mayfair’s Gymkhana aren’t rooms, they’re vaults (and one has a wine cellar). Which is perfect if you’re James Bond, allergic to sunlight, or just need a truly memorable, intimate space for a private dinner. There’s red leather banquette seating, a range of excellent contemporary Indian set menus, recommended florists, music options, and their cocktail lounge, 42, is open until 2am—you can also rent it. Reservations are released two months in advance, so set your alarm for 6am that day. Your best bet is planning the best London day off known to lamb chop-lovers and opt for one of the weekday lunchtime bookings. If you’re really struggling, sister spots—Bibi, Brigadiers, and Ambassadors Clubhouse—usually have more availability." - heidi lauth beasley, sinead cranna
