When someone asks where to throw a birthday party in Bainbridge, we say come see the building first. Old Post Office sits on the downtown square in a structure built in 1914, and the room itself sets the tone before a single cocktail gets poured.
Old Post Office provides birthday party options in Bainbridge with spaces such as the ballroom, Postmaster’s Parlor, and Mailroom Speakeasy. Guests can choose settings based on party size and style, with access to historic architecture, bar service, catering options, event planning support, and distinctive features throughout the restored 1914 building.
We’ve watched plenty of birthdays come through these doors. Some take over the whole ballroom. Others tuck into the Postmaster’s Parlor for something quieter, and a growing number head downstairs to the Mailroom Speakeasy.
Planning a Birthday Party at a Bainbridge Landmark
Once you know you want a birthday here, the next step is matching the right floor to your guest list. We’ll walk you through the ballroom, the Postmaster’s Parlor, and the Mailroom Speakeasy, then cover what’s included with each booking, from the bar to decor to the cigar lounge, so you can pick the setup that fits your night best.
The Spaces, and How a Birthday Crowd Moves
Most birthday nights start in the lobby, where the original Terrazzo floor and its inlaid wood trim greet guests at the entrance. This same space doubles as the full bar for the main floor. From there, guests move into the main ballroom, built to handle any configuration of tables and able to accommodate several hundred people for a livelier celebration.
If the guest list is smaller, the Postmaster’s Parlor is worth a look: a private rentable room off the main floor with a smart television and its own bar service, overlooking the downtown square. Look up in the ballroom, and you’ll spot a catwalk hidden in the ceiling. Down the back hallway sits a large walk-in vault with a door as heavy as a car, a favorite spot for an interior photo.
Why Birthday Parties End Up in the Mailroom Speakeasy
The Mailroom Speakeasy is an underground, Prohibition-inspired lounge beneath the main building, with its own back entrance and a velvet-draped feel that’s different from the ballroom upstairs. Birthdays are named directly among the events the space is built for, along with engagement parties, corporate mixers, and rehearsal dinners.
A private birthday booking comes with private use of the bar, a custom menu of cocktails and small plates, and help with entertainment booking and decor planning. Past themed nights have ranged from Gatsby-style parties to candlelit absinthe tastings.
Available Features and Details to Confirm
A birthday booking through the main event space comes with a full-service bar, customizable decor, and an event planning team. The cocktail menu changes seasonally, with a full wine list and zero-proof options. For something extra, there’s a separate, well-ventilated cigar lounge with a curated selection of premium cigars, plus a complimentary pool table. A full catering kitchen is on site, and food from The American, the venue’s downtown restaurant partner, is available exclusively to Old Post Office guests.
The building has ADA ramp access at the rear, with an ADA bathroom near the main floor bar. We’re open Thursday 5 to 10 PM and Friday through Saturday 5 to 11 PM; Sunday through Wednesday are closed. Old Post Office is a recipient of the Georgia Trust for Historic Preservation 2026 Excellence in Rehabilitation Award.

However you picture the night, a ballroom full of friends, a quiet toast in the Postmaster’s Parlor, or a themed evening behind the speakeasy door, we want your birthday at Old Post Office to feel like it belongs to you. That’s what a building this distinctive is built for.
