City Post offers two distinct spaces to host private parties in our beautifully restored historic post office. Private dining in the Mailroom is the perfect choice for intimate parties of 6-12. For larger parties (up to 80 seated or 110 for a cocktail party), Ada Talbot Hall, located on the second floor, features a private bar, custom dance floor & stage, a state-of-the-art audio/visual system, and private washrooms.
