A seemingly ordinary building not far from the famous bridge on the Chicago River, there is no beautiful large glass curtain wall, but it is the local headquarters of the three major US TV stations in Chicago. Every night, the lights are searched on the exterior walls of the building, and the yellow softness is in stark contrast to the surrounding blue interior, lighting up the different skylines on the Chicago River. The building is not far from Sheraton, you can find it within a few steps.
