The Secret Mermaid is kind of, well, secret. It's probably nowhere to be found when the sun's still up, as salad bar Shinkansen operates this spot in the day. This elusive tasting room serves some of the most bizarre spirits you've ever heard of. Anyone up for Bakon Vodka or Smoked Salmon Vodka? If not, they bring in several other American spirits that are completely new and unique to Singapore, such as Berkshire Mountain’s Greylock Gin, which is rated the #1 gin by the New York Times.
