For once, the term ‘underground’ really is an apt description for this supper club, hosted by the Basement Galley in the quintessential London setting of a tube train. A 1967 Victoria Line tube carriage, no less. Sadly, the carriage is no longer in use, so you won’t be stopping at Warren Street station in between courses – though if anyone from TfL is reading, that would be a great marketing wheeze (and would give a whole new meaning to the Oystercard). Instead, it’s permanently off-track at the Walthamstow Pumphouse Transport Museum. An ‘off-peak single, from starter to dessert’ costs £35, for a meal that includes duck and cherry terrine, fizzy cocktail jellies, Louisiana-style shrimp and grits, and fig and lavender tart. You know how crowded the tube can get, so do book ahead.
