400 East Randolph Street Condominiums or simply 400 East Randolph is a 40-story high-rise in Chicago, Illinois, designed by Reinheimer & Associates. The building primarily consists of residential condominiums, though there are a few businesses and restaurants also located in the building. Situated on East Randolph Street on the New Eastside, the building sits between the Buckingham to its west and Harbor Point to its east. Two parks, Millennium Park and Lakeshore East Park, are immediately located to 400 East Randolph's south and north faces respectively. It is one of the buildings in the area that predates the new surrounding Lakeshore East development.
