35 East Wacker, also known as the Jewelers' Building,[5] is a 40-story 523 ft (159 m) historic building in the Loop community area of Chicago, Illinois, United States, located at the intersection of Wabash Avenue and East Wacker Drive, facing the Chicago River.

There was no access between the offices and the parking garage, except at the Lower Wacker Drive level, where drivers would leave their cars with an attendant.

the French-American Chamber of Commerce in Chicago is a tenant,[12] and the showroom of architect Helmut Jahn was atop the building inside the dome, which was also once a restaurant called the Stratosphere Club, often erroneously said to be run by Al Capone.

[5] (In reality, the Stratosphere Club opened in 1937, long after Capone was imprisoned and too late for the building to have been an illegal speakeasy.

)[13] The building is currently being renovated, by Goettsch Partners, and the façade is being maintained, but the interiors converted into a more modern configuration.
