It may be time to blow the dust off your old flapper girl costumes because there's a new speakeasy in town. If you want a true Prohibition-era experience, you can access this secret bar-by-night which happens to be a former filling station. This all-new retro-inspired hidden bar in Atlanta has all the Great Gatsby vibes one could wish for.

The Third Door held its grand opening on the night of August 21st near Marietta Square. The restored 1920s gas station holds true to the speakeasy concept as a daytime business that transforms into the Roaring 20s with a little twist by nightfall.

All the exciting "Jazz Age" entertainment starts as soon as the travel trailer showroom, Happier Camper, closes its doors for the day.

Once you step inside through the alley door, you'll be swept away into a time machine of tin ceilings, prestigious cocktails, original polished American pine wood bars, Victorian chaise lounging, and a gallery with stage curtains.

After hours of dancing Daisy Buchanan-style (and sipping on her namesake cocktail), you can step outside to the pump yard for some fresh air and fun.

Through enormous glass garage doors, you'll enter a wonderland of games, open-air seating, Biergarten tables, and drinks served from The Third Door’s sister brand, Temperance Trailers vintage mobile bars.

If you like to splurge on lavish libations, The Third Door is your go-to.

Sip on pure elegance with one-of-a-kind elixirs like the "Lost Generation" with Calvados, Cognac, banana, and chai or the "Gatecrasher" with rye, Pedro Jimenez Sherry, Amaro, cherry, black pepper, Peat, and Peychaud's. They even have a secret cocktail menu.

Although food is not yet available here, the owners plan to roll out some food trucks in the future as reported by AJC.

Next time you're in the mood for an atypical night out on the town, hit up this late-night Church Street hideaway, open from 5 p.m. to midnight Tuesday through Thursday and 5 p.m. to 1 a.m. Friday and Saturday.
