Four Pillars Gin Laboratory is a small batch distillery and bar in the historic Bussel Bros building in Sydney's Surry Hills. This gin-soaked bar is hidden behind an unmarked door on the corner of Fitzroy and Crown Street. Set across two floors with three distinct venues inside, it's a veritable gin lover's paradise complete with a gin boutique, a laboratory for masterclasses and experimental gin things and, the pièce de résistance, a hidden laneway bar called Eileen's that features a totally breathtaking 11-metre juniper-blue concrete bar as its centrepiece.
