Named the UK’s Best Specialist Bar by CLASS Magazine for three consecutive years, Black Rock really has been a game changer for the London whiskey scene. The dimly lit underground bar is small enough to have no bar, only a drinks trolley, which means the bartenders are free to roam and converse. Choose a whiskey from the ‘library’ or from the menu, which also offers whiskey cocktails and small bites. The bar’s centrepiece is an 18ft old oak tree trunk which acts as an ageing system.
