One of the areas hit hardest by the economic fallout of the ongoing COVID-19 outbreak in America is the restaurant industry and with a number of states that still have strict social distancing restrictions in place, it may be quite some time before it's business as usual in dining rooms across the country.

A few national chains as well as some independent locations have already had to react with layoffs, furloughs, and in some cases, closures, while others have transitioned to a less profitable take-out model.

But the worst may be yet to come.

USA Today is reporting that seven well-known national restaurant chains are slowly moving toward potential bankruptcy if things don't improve drastically in the near future. The latest figures from S&P Global Market Intelligence show that sales at restaurants and bars fell 26% in June.

Of the chains in trouble, four currently have Sioux Falls locations, while a fifth is planning to open here either sometime this year or in early 2021.

Currently, the chain has a pair of Sioux Falls locations - inside the Empire Mall and at 3221 East 10th Street.

Construction on the city's first Dave & Buster's was underway at Lake Lorraine when the pandemic hit and has now been on hold since April.

Nationally, the chain has a 16.1% chance of defaulting after posting a loss of $43.5 million last quarter.

The two other chains which made the most vulnerable list, that don't have a Sioux Falls presence, are BJ's Restaurant, whose closest location is in Wichita, Kansas (470 miles away), and The Cheesecake Factory which has a restaurant in Omaha (180 miles away).
