“Located in the sky lobby on the 11th floor of the Centrust Miami Tower, Pei’s Place cafeteria was named after the building’s architect I.M. Pei. The logo was created under the art direction of designer Michael Bierut, while working at Vignelli Associates in the late 1980s. The logo uses two different typefaces; ITC Didi and ITC Avant Garde Gothic. The colors that are used represent the stop, yield, and go of a traffic light.” — Flora Qiangwei Zhu
