The 2026 Annual Serendipity Holiday Soirée - Private Dinner in The Mystery Room
Date: Tuesday, December 1, 2026 | 5:00 PM - 9:00 PM MST
Location: The Mystery Room in the Arizona Biltmore, 2400 E Missouri Ave, Phoenix, AZ 85016, United States
Capacity: 30 members
Hidden behind an unmarked doorway on the second floor of the Arizona Biltmore, the Mystery Room was a favorite hideaway of the powerful and famous during Prohibition - legend has it Clark Gable and Carole Lombard requested the same guest room on every visit simply because it sat closest to the secret door.
Disguised as the hotel's "Men's Smoking Room" to keep it hidden in plain sight, the space still carries its 1929 design: a restored gold-leaf ceiling, historic photos, and an ornate fireplace.
Legend also holds that the room was built with hidden getaway doors, and a rooftop lookout would flash a warning light if police were spotted approaching - giving guests time to slip out before getting caught. Normally reserved for private events or the occasional history tour; for one night, it's ours.
✨ What’s pouring
A seated dinner follows, beginning with a chilled seafood display of half lobster tails, colossal shrimp, and West Coast oysters, followed by carving stations featuring peppercorn-crusted beef tenderloin, cowboy-crusted ribeye, and honey-glazed salmon, each with its own accompaniments.
At the bar, the evening stays firmly in the Prohibition era, with a hand-selected wine list and a cocktail menu curated especially for the evening - French 75s, Sidecars, Hemingway Daiquiris, Bee’s Knees, and the Biltmore’s own 1935 Martini. The carving stations, cocktails, and wine will continue throughout the evening - all included in your ticket.

*Kosher food is available upon request at checkout.
🛎 Make a Night of It
Partners and their guests are welcome to take advantage of our exclusive group rate at the Arizona Biltmore.
The Arizona Biltmore has welcomed guests since 1929 - and it is one of the most extraordinary art deco landmarks in America. Designed by Albert Chase McArthur with Frank Lloyd Wright as consulting architect, the hotel is built entirely of concrete "Biltmore blocks" cast in 34 different geometric patterns inspired by the trunk of a palm tree. Clark Gable, Marilyn Monroe, Frank Sinatra, and Sammy Davis Jr. all called it home. The Tequila Sunrise was invented at its bar.
Our exclusive rate - $319/night, a fraction of what a Biltmore stay typically runs this time of year.

Reservations must be made by November 1st to take advantage of our exclusive rate.
The rate is also available for up to three nights before and after the event, based on availability.
PRIVATE DINNERS
Smaller, ticketed, more exclusive evenings - often paired with a flagship gathering, sometimes standalone - built around a distinctive venue or experience rather than a large guest list. Capacity is intentionally limited to roughly 20-30 members, and seats go quickly.
