Berlin's most successful underground nightlife impresario, known only by the mysterious moniker Cookie, revives hotel dining with this cutting-edge vegetarian restaurant hidden in the Westin Grand. The entrance is marked only by a jumble of light bulbs dangling from an awning; inside, guests navigate a maze of nondescript hallways to reach the industrial chic dining room. Chef Michael Kempf, of the Michelin-starred Facil, has collaborated on imaginative dishes like pumpkin soup with chutney and cashews and cauliflower cannelloni with wintercress. Even the most old-school Berliners love it for its affordable three-course menus and surprisingly good service.
Tip: Go on a Thursday night, when the downstairs Cookies club is in full swing (prix fixe, $37).
