Easily the warmest and most charming location in San Francisco City Hall, and famous for hosting Marilyn Monroe's wedding to Joe DiMaggio, with its golden railing back in the day.  The Mayor's Balcony is private, yet completely ensconced in the center of San Francisco City Hall. Featuring a short set of stairs to make your dramatic entrance down the aisle, and overlooking the famous grand staircase, the one-hour floor rental option costs $1200 for the hour, and you may rent chairs from the SF City Hall events department. You may have 40 seated guests with 20 more standing.
