This Shuangjing bar is a huge, cavernous basement inside a residential compound. Run by networking guru Brian Gale (Network Club), Hidden Lounge looks better-suited to hosting events and private parties than as a place to hang out every other night. The bar offers live music, wine tastings and many more events besides. And there’s nothing stopping you dropping in unannounced, slumping deep into cozy armchairs or retreating into a shoes-off alcove with a gin and tonic or Long Island.
