This cool bar is the failsafe place where young creatives go to drink affordable classic cocktails when everything else is shutting down. With its edgy location (in an underpass, hence the name), chandelier-lined ceiling, moody red-lit interior, and mismatched seating, it sits somewhere between kitsch and nonchalantly shabby. There’s a house-party vibe to it all, complete with a DJ spinning low-key techno music until dawn.
