While rooftop bars feature impressive views — and sometimes from nosebleed-inducing heights — there’s a different sort of attraction to bars that are hidden underground or underwater since they offer a shared sense of intimacy and are often in spectacular or historic hideaway venues. These 9 subterranean bars from the Maldives to lower Manhattan each have their own visual flair and special atmosphere — the one thing they all have in common: they’re not recommended for anyone who gets claustrophobic.1.
