The Treasury is an upscale cocktail bar and lounge housed in a historic 1916 Beaux Arts building at the heart of San Francisco's Financial District, formerly the headquarters of Standard Oil Company. The elegant 1,500-square-foot space features floor-to-ceiling windows, double-height ceilings, a dramatic curved soapstone bar, and ornate design elements including a glass chandelier, stained glass globes, and gilded mosaic-tiled archways that evoke Gatsby-era sophistication. The bar specializes in craft cocktails ranging from $17–$20, including signature creations like the Bay Roots and Treasury Espresso Martini, complemented by premium highballs, low and zero-proof options, craft beer, curated wine, and chef-caliber bar snacks. The refined atmosphere makes The Treasury an ideal destination for daytime lunch service and sophisticated evening cocktails in one of San Francisco's most architecturally distinguished venues.
