Old Post Office

Spanning an entire city block in the heart of downtown Chicago, the Old Post Office is one of the most architecturally commanding event venues in the country. As an experienced event decorator at the Old Post Office, Yanni Design Studio delivers museum-scale décor and production-driven event design created for clients seeking unparalleled impact and prestige.

Our photo galleries highlight monumental floral installations, grand ceiling treatments, custom staging, luxury lighting systems, dramatic entrance designs, and fully branded environments. With its massive proportions, soaring ceilings, and historic grandeur, the Old Post Office is ideal for ultra-luxury weddings, corporate milestone events, large-scale galas, and international brand experiences. This venue demands—and rewards—high-level design vision, precision execution, and bold creative investment.
