WDIV reports that there are no reported injuries due to the fire.
The restaurant, located at 2520 Michigan Ave., opened in early 2016 and has been popular ever since. It was recently named to the list of James Beard 2017 semifinalists.
According to reports, the building is badly smoke and water damaged.
Update 2: It doesn't appear that interior damage at Katoi is going to keep the trendy restaurant benched for long. Katoi chef Brad Greenhill told the Freep, "With the love and support from our friends and neighbors, we'll rise again from the ashes ... with a vengeance," while a post on the company's Instagram's page promises that Katoi is bigger than any building and will be back in action soon.
