Hidden cocktail lounge inside Tropics Ale House at Discovery Bay. Darker, quieter, multi-page craft menu, deeper spirits — and one of the few non-hotel Waikiki bars open until 2 AM with serious cocktails.
If you've already done the touristy mai-tai-on-the-beach thing and want a grown-up drink at 11 PM without paying hotel-bar prices, The Barrel Room is the answer. It's not a scene, it's not a club — it's the back room of a sports bar that takes its cocktail program seriously and stays open until 2 AM. Walk through Tropics, follow the signs, and you've found one of Waikiki's quieter late-night moves.
The tucked-away cocktail lounge inside Tropics Ale House Waikiki, accessed through the main Tropics doors at the Discovery Bay corner of Waikiki. Where the front-of-house Ale House is loud, screen-heavy and tacos-and-tap-beer focused, The Barrel Room flips the script: it's the after-dinner room, darker, quieter, built around a multi-page craft cocktail menu and a deeper spirits selection. The format is "stay through the night" — happy hour rolls in at 3 PM and the doors stay open until 2 AM.
$8 craft cocktail — strongest price-to-quality ratio in this part of Waikiki where most cocktails cross $15.
