New York Post: Conde Nast has told employees to start tweeting about its new cafeteria at 1 World Trade Center in an effort to generate buzz, after the company left its old 4 Times Square headquarters with its fabled $30 million Frank Gehry canteen. Signs posted in the new cafe read, “Instagram Me! Upload photos using the hashtag #condecafeteria,” and staffers are told to follow the canteen’s feed, @cafe1wtc.
