Door 74: Amsterdam, the Netherlands

This Amsterdam stalwart speakeasy gets continued high marks for its consistently delicious cocktails, intimate booths and modern reservations system. Just call 31-0/877-844-980 in the morning to book a table and text the same number in the evening to confirm. Upon settling in, the menu arrives with specific instructions to further the clandestine nature of the place. Smokers are asked to walk to another bar, down the road, before lighting up—lest they signal the secret address to passing pedestrians—and patrons are instructed to say their farewells before exiting the bar.
