Host your celebration in the room that once housed Chicago’s legendary Pump Room. Inside Ambassador Gold Coast, the Ambassador Room pairs the history of a hotel opened in 1926 with glowing globe lights and a distinctive setting for wedding receptions, rehearsal dinners, birthdays, company celebrations and private dining. Make the evening your own, from a seated dinner to a cocktail reception with room to mingle. Our events team can help shape the layout, menu, beverage service and flow around your guest list. In-house catering and bar options can be discussed in your proposal, along with staffing, setup and any additional event needs. The Ambassador Room accommodates up to 350 guests in total; seated capacity varies by layout. Your booking is for the agreed space and arrangement. Other hotel venues, including the Terrace on Seventeen and Champagne Room, can be explored separately if you are planning several moments across an event or wedding weekend. Guest rooms and suites keep visiting friends, family and colleagues close, with Chicago’s lakefront and Michigan Avenue nearby.
