Speakeasies are an ever-growing trend. There's an amusing novelty to them— typically hidden behind or under some front business, insusceptible to the average eye. Visitors are forced to discover a secret door or know a password in order to gain entry. For example, The Garret, located in New York City's West Village, requires visitors to walk through a Five Guys and discover a door for entry. Then there's Please Don't Tell on St. Marks Place, visitors are required to step inside a British telephone booth and pick up the phone for a door to open. We've compiled a list of the top must-visit speakeasies around the nation for you to take a nostalgic trip back to The Great Gatsby-era.

1. Garage, 503 Colorado St, Austin, TX

This bar is seriously in the most unexpected of places: a parking garage. The only indication of its existence is a turquoise neon sign. The drinks are uniquely Texan, featuring Southern ingredients like jalapeno and honey. Go for the "Forked Tongue," made out of sotol, jalapeno, lime, green chartreuse, and saline.

2. Bathtub Gin, 132 9th Ave, New York, NY

Bathtub Gin sits behind the most unsuspecting of places: a calm coffee shop. The bar offers up sets of $15 cocktails that will knock you off your feet, some of them made of high-grade bathtub gin and absinthe. It also serves up your standard bar fare, but in luxury form, like fresh herb fries with truffle aioli.

3. The Blind Lion Speakeasy, Rapid City, South Dakota

In order to gain access to this speakeasy, keep an eye locked on its Facebook page or get well acquainted with one of the bartenders. Once you do that, the owner will text you instructions on how to access the bar. Gaining entrance is so complicated, we recommend watching this video for a clear understanding.

The bar comes with these simple rules:

Slow Down [Live in the Moment]

Challenge Your Senses [Let Us Create An Experience for You]

Your Cocktail is Handcrafted [By Passionate Mixologists with Fresh and Quality Ingredients. Please Be Patient]

Relax [Please Refrain from Cell Phone Use. Calls Can Be Made from the Convenience of the Public Phone Booth]

Shh… [Please don't share the passcode]

4. Please Don't Tell, 113 St Marks Pl, New York, NY

Please Don't Tell is located inside of Crif Dogs, a hotdog joint. The whole process of cramming into a telephone booth with your friends and picking up a phone for a secret door to appear is quite amusing. Inside, you'll find a swanky bar, serving top-shelf cocktails created by mixologist Jim Meehan. One honorable mention is an old fashioned made with bacon-infused bourbon and maple syrup.

5. Atwater Alley, 4900 McKinney Ave, Dallas, TX

This Texan speakeasy is tucked in behind a dark alley, next to Henry's Majestic Bar. Visitors suggest you simply tell the bartender your liquor of choice and watch them put their creative action to work as they mix you a one-of-a-kind drink.

So next time you're feeling covert and adventurous, hunt around for these hidden gems.
