‍‍Tucked away behind a bamboo wall, The Green Lady Cocktail Room at the White Sands Hotel in Oahu offers a speakeasy vibe that transports you right back to the Roaring '20s.

This hidden gem serves up a Prohibition-inspired cocktail menu in an intimate setting that seats just 20, making every night feel like an exclusive affair.

For hotels looking to spice up their offerings, The Green Lady serves as a perfect example of how you can create a unique experience out of small space in the hotel.

Oh, and in true Prohibition-era style, to gain access to this joint, you'll need to ask reception for the "Green Lady" or request Room 8.
