In March, restaurants had the highest number of business closures, compared to other industries, and have continued to close at high rates. Of the businesses listed on Yelp that have closed, 17% are restaurants, and 53% of those restaurant closures are indicated as permanent.
Restaurants run on thin margins and can sometimes take months or even years to break even, resulting in this higher rate of permanent closures.
