Built in 1927, the 4-star Millennium Knickerbocker Hotel Chicago has a colorful history. Al Capone’s brother once ran a casino on the Penthouse Floor, and in the ’70s, it had a stint as the Playboy Towers. We’ve housed such luminaries as John F. Kennedy, Richard Nixon and the Rolling Stones.A landmark in its own right, our hotel has 306 guest rooms and suites, and 18,500 sq ft (1,719 sq m) of meeting space, including the iconic Crystal Ballroom, complete with illuminated dance floor and gold-gilded domed ceiling. Drink in the 1920’s cocktail menu at Martini Bar, or savor farm-to-table cuisine at NiX. Located at the start of the Magnificent Mile, we're also an easy walk to 360 Chicago and the Museum of Contemporary Art.Book here for our Best Price Guarantee promise.
