Location: Platform 18 at Century Grand, 3626 E Indian School Rd, Phoenix, AZ 85018, United States
Capacity: 45 members
All aboard!
This December, Serendipity boards a 1924 Presidential Pullman-inspired train car for a journey through the snow-capped Colorado Rockies - and we mean that more literally than you might expect. Platform 18 is hidden inside the Century Grand in Phoenix, but once the doors close, the outside world disappears. The windows come alive with six hours of real footage filmed aboard the Durango & Silverton - one of the last open-air train cars in North America - rolling from Durango to Silverton in the tail end of a great snowstorm, floor humming, whistle sounding somewhere ahead. For the next four hours, it is 1924, and you are somewhere in the mountains.
Here's the story built into the room: somewhere on this train, a bootlegger is moving contraband across the Rockies during Prohibition - it's the whole reason for the snowbound pass outside the window and the hum in the floor. It's a train with a purpose, not just a backdrop.
But the cocktails in your hand are telling a different story: ours. We've crafted a custom menu of prohibition-era drinks that trace the Serendipity story instead - every drink a character, every glass a scene. It's the kind of narrative that feels made for Serendipity - a little mysterious, a little glamorous, and entirely immersive.
Platform 18 is intimate by design - just 45 passengers - with warm wood interiors, green velvet curtains, golden light, and a drinks program so extraordinary it has been named one of the 50 Best Bars in North America twice over and won Best U.S. Cocktail Bar in 2023. Tonight, every seat is ours.
Outside the windows, the Rockies in winter. Inside, prohibition-era jazz, the right people, and a very good drink in hand.

🛎 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.
