Brooklyn Underground Cocktails

Le Boudoir: A Rococo Speakeasy in an Abandoned Subway Tunnel

Brooklyn, New York, United States

Why it’s cool

This lavish cocktail den occupies a hidden chamber of the world's oldest subway tunnel, blending 19th-century transit history with the opulent, gilded excess of Marie Antoinette’s court.

Northeast Hidden Gem

Beneath the surface of Brooklyn’s Atlantic Avenue lies a secret that bridges the gap between th-century French excess and th-century American engineering. While diners at the restaurant Chez Moi enjoy their meals, a select few slip through a nondescript bookshelf to enter Le Boudoir.

This subterranean lounge isn't just a basement bar; it is a meticulously crafted homage to Marie Antoinette, carved directly into a forgotten section of the world’s oldest subway tunnel.

Why It Stands Out

The venue’s physical foundation is rooted in the Atlantic Avenue railroad tunnel, a transit marvel built in that served the city for only sixteen years before being sealed away. This historic tunnel shares its subterranean elegance with the nearby Old City Hall Station.

For decades, the space was a thing of urban legend, briefly rediscovered by engineer Bob Diamond in before being shuttered again in . The current iteration began in when owners Tarek Debira and Patricia Ageheim decided to investigate a hunch about their restaurant’s basement walls.

After breaking through the brick, they revealed a hidden chamber bordering the historic tunnel. A similar sense of discovery surrounds The Ramble Cave, another forgotten underground passage.

Today, the space is a masterclass in Rococo flair. The atmosphere is thick with gilded accents and velvet textures, featuring authentic touches like an actual doorknob salvaged from Versailles.

Even the beverage service leans into the theme; a bust of the ill-fated queen serves as a functional beer tap. The menu complements the decadence with snacks like truffle-mushroom croquettes and crispy frog legs, paired with botanical cocktails like the kaffir lime-infused Rococo or the lavender-scented Smoke & Mirrors.

Before You Go

While the bar was once a strictly first-come, first-served affair, guests can now book reservations through the official website to secure a table. For those seeking entertainment alongside their spirits, the venue hosts live jazz on Monday nights and brief burlesque performances on the weekends.

If you plan to catch the burlesque show, arrive early to find a spot and remember to bring cash for the performers.

Questions worth answering

How do we find this place?

Look for the bookshelf inside the restaurant Chez Moi. It's the entrance to a space carved into the Atlantic Avenue railroad tunnel from 1844.

What's the best way to secure a seat?

We suggest booking through their website to get a table. While it used to be walk-in only, you can now reserve a spot in the small room.

Is there any entertainment scheduled?

Monday nights are for live jazz. If you show up on the weekend, you'll see burlesque sets that last about fifteen minutes.

What's the story behind the design?

The owners found this chamber after breaking through basement brick in 2014. It's now a tribute to Marie Antoinette, complete with a doorknob from Versailles and a beer tap shaped like her bust.

Le Boudoir

It started in , when Marie Antoinette, who would soon become infamous for her indulgence, was born in Austria. Or perhaps, it started in , when Brooklyn built the Atlantic Avenue railroad tunnel —the world's first subway.

Like the guillotined queen, the tunnel had a short life, functioning as an active train pathway for only years. But also like the queen, it had a long, mythic afterlife: first, as a receptacle of rumored monster rats, then as part of a quirky Brooklyn tour, and now, as a Marie Antoinette–themed speakeasy.

After it closed, the tunnel sat abandoned for years, until an intrepid engineer and history buff named Bob Diamond rediscovered it in . He offered tours through a manhole until the city shut him down in .

Again, the tunnel was sealed off and abandoned. In , Tarek Debira and Patricia Ageheim were renovating their Atlantic Avenue restaurant, Chez Moi, when Debira had an idea: Why not hammer through the basement wall?

They both had a hunch that their property bordered part of the subway tunnel. So when Debira burst through the basement walls to reveal a hidden chamber, he knew he had hit on something special.

Debira and Ageheim incorporated the space into a bar called Le Boudoir that is both literally and figuratively underground. Visitors to Chez Moi can access the bar through a fake bookshelf in the restaurant.

Once below, they are greeted with a gilded world including rococo-style furniture, a Marie Antoinette bust that doubles as a drinks tap, an antique-style wooden toilet, and a doorknob from Versailles itself . Visitors can snack on crispy frog legs and truffle-mushroom croquettes while sipping cocktails such as the Rococo, flavored with oolong tea and kaffir lime, and the Smoke & Mirrors, flavored with blueberry-lavender cordial and bergamot.

Visit Le Boudoir for lavish fun—or to hide out underground when the masses pull out the guillotine.
