There's a lot of good reasons to head down rather than up to a rooftop bar when you're feeling parched. Underground, it's always party o'clock, because even if it's 2pm, it feels like after dark. Plus you have no external cues as to the lateness of the hour, so a quick drink can turn into a big night very easily. Drinking below street level is also deliciously climate controlled so on a blazing hot summer's day, or in a torrential downpour, your best bet is posting up in one of Sydney's best booze cellars.
