A guest recently described their first visit to the Mailroom Speakeasy as the kind of night where time seems to slow down. High ceilings, warm lighting, and a live band tuning up in the corner set the tone before a single drink was even poured. That’s the welcome we hope every visitor gets at Old Post Office in downtown Bainbridge, Georgia, whether it’s their first trip down the back stairs or their tenth.
The Mailroom Speakeasy beneath the historic Old Post Office in downtown Bainbridge, Georgia, is a Prohibition-inspired lounge with preserved original architectural details, high ceilings, and warm lighting, accessed through a rear entrance. Live jazz fills the room on select nights each month, while Mr. Penny’s room offers a quieter, candlelit corner for smaller groups, and the venue is open to walk-in guests Thursday through Saturday evenings.
A Night Inside Bainbridge’s Best Kept Secret
The Mailroom sits below Old Post Office, a historic building dating back to 1914 that anchors the town square in the heart of SOWEGA. Guests who find their way to the back entrance step into a Prohibition-inspired lounge that still carries the character of the original building, even after a full renovation.
Stepping Through the Door
One recent guest said the high ceilings and soft lighting made the whole room feel almost cinematic. That’s not by accident. When we turned the basement into the Mailroom, we kept as many original architectural details as we could and paired them with modern finishes, so the space feels luxe without losing the history underneath it.

Live Jazz Sets the Tone
Live jazz fills the room on select nights each month, and it’s a big part of what makes the Mailroom feel less like a bar and more like a scene out of another decade. One guest remembered a saxophone warming up in the corner just as they walked in, and by the time the band settled into its first set, the whole room had come alive. For a lot of visitors, that first note is the moment the night really starts.
Finding Mr. Penny’s Room
Not everyone notices the door tucked toward the back of the speakeasy. Behind it sits Mr. Penny’s room, a smaller, candlelit space built for conversations that don’t have to compete with the band up front. One visitor described stumbling onto a hidden room later in the evening and staying there far longer than planned, talking with people they had just met an hour before. That’s exactly what the room is for.

The Kind of Night That Turns Strangers Into Friends
There’s something about the Mailroom that gets people talking to whoever is standing next to them. A guest recently told us they ended up dancing with a group of strangers who felt like old friends within minutes, and by the end of the night, nobody was in a hurry to leave. Whether it’s the music, the low light, or just the setting, nights at the Mailroom have a way of running long in the best sense.
Conclusion
A trip to the Mailroom Speakeasy is rarely just one drink and a quick exit. Between the live jazz, the hidden corners, and a building that has been part of Bainbridge since 1914, it is easy to lose track of time once you’re downstairs. If you haven’t found your way through the back door yet, there is a whole other side of Old Post Office waiting for you.
