Besides being hidden, Le Boudoir is unique for a very special architectural feature. Accessed via a fake bookshelf within the restaurant Chez Moi, Le Boudoir is partly located inside remnants of the legendary Atlantic Avenue tunnel, the world’s oldest subway tunnel from 1844. The decadent decor of the bar is inspired by a secret boudoir of Marie Antoinette in Versailles.
