Mayor Rahm Emanuel on Wednesday demanded another round of cost-cutting at Taste of Chicago after last year’s shrunken, revamped and bumped Taste lost $1.3 million, $300,000 more than the year before. “I told the team at Cultural Affairs to re-think [the Taste]. Attendance was up. Revenue was up. The problem is, costs were up. And I said, ‘We have to come down on that,’” Emanuel said.
