The Atrium Club at 25 East Washington is a 15,000 SF amenity floor on the 7th floor, designed to host everything from intimate gatherings to large-scale events for up to 350 guests. The space blends the building's historic architectural character with a clean, contemporary finish — timeless and modern at once. Perfectly situated steps from Millennium Park and right off Michigan Avenue, guests are never far from world-class dining, shopping, and Chicago's most iconic landmarks. Flexible Booking Options The Atrium Club can be booked in full, by section, or by individual room — making it just as suited for a small team meeting as it is for a 350-person gala. Whether you need just the conference room, the courtyard, the game room, or the entire venue, the space can be tailored to fit your event size and budget. Layout & How the Space Works The Atrium Club is built around a central indoor lounge and sunlit atrium, with sliding doors that open directly to a 3,000 SF furnished outdoor courtyard. The result is a seamless indoor-outdoor flow that shifts the tone of any gathering. The flexible conference center accommodates 10 to 150 guests and can function as one large room or divide into two separate rooms for smaller, concurrent events. Beyond the main event spaces, the floor offers more than 50 integrated workspaces, multiple lounge areas, private phone booths for calls or one-on-one virtual meetings, a welcoming indoor/outdoor bar, and a dedicated game room. What Works Well Here The Atrium Club is an ideal setting for weddings, reunions, fundraisers, conferences, corporate receptions, networking events, client dinners, team off-sites, product launches, and professional workshops. The variety of zones means guests can move fluidly between focused work, casual conversation, friendly competition, and celebration — all within the same footprint.
