We've seen bars hidden behind a phone booth, and even behind a wall of kegs — but never one tucked away behind a wall in a basement restroom. Until now. PortSide Parlour is one of the most difficult to find bars in London Fields, tucked behind the wall of an unmarked bathroom in the basement of Off Broadway. Once inside, you'll find yourself in a richly furnished and appropriately dim space, filled with terrific music, and featuring a bar that serves 50 of the world's finest rums — thanks to a partnership with Jamaica's finest Rum Appleton Estate — and cocktails worthy of a secret rendezvous.
