Founded by Joseph Borowski first as a hospitality school which morphed into a watering hole, the bar – which has previously billed itself as 'invitation-only' with hard-to-find, unlisted addresses – is set above new restaurant Bistro 11. In Shanghai, walk-ins are welcomed (just find the unmarked black door), though reservations will ensure that you nab one of the 17 bar seats, which if the other incarnations are any indication, will be highly sought after. The twist? There's no menu at this 'cocktail concierge service'.
