Maybe the apocalypse really is upon us. Keith McNally, who usually limits his brushes with the press to indignant e-mails, is sitting down for an hour-long interview with Minetta maven Martha Stewart. He’ll appear on “At Martha’s Table” today at 4 p.m. on Martha Stewart Living Radio (SiriusXM channel 110), and you can call 1-866-675-6675 with any burning questions about secret numbers.
