Union Square/Theater District – Mason St & Geary St This premiere sign is located at the heart of the Union Square Theater District, directly across from both the American Conservatory and Curran Theaters. Surrounded by an array of dining and shopping options that cater to both art-goers and tourists, this wallscape creates a lasting impression as there is limited OOH signage in the Union Square area. Additionally, this area also houses the Clift Hotel, chic cafés, and high-end retailers.
