Washington, Dec 8 (IANS): Due to prolonged restrictions and closures due to the raging coronavirus pandemic, more than 110,000 restaurants across the US have had to completely down its shutters, according to the National Restaurant Association.

"The vast majority of permanently closed restaurants were well-established businesses, and fixtures in their communities. On average these restaurants had been in business for 16 years," Xinhua news agency quoted Sean Kennedy, executive vice president for public affairs with the association, as saying in a letter to congressional leadership sent on Monday.

"Only 48 per cent of these former restaurant owners say it is likely they will remain in the industry in any form in the months or years ahead," Kennedy wrote in the letter, sharing key findings of a survey of 6,000 restaurant operators and 250 supply chain businesses, which was conducted last month.

"What these findings make clear is that more than 500,000 restaurants of every business type -- franchise, chain, and independent -- are in an unprecedented economic decline," he said, adding the restaurant industry simply cannot wait for relief any longer.

Kennedy noted that the lack of progress in the Covid-19 relief talks among congressional lawmakers has led too many restaurant operators to giving up waiting for relief and closing down for good.

"Since our last update to you, less than three months ago, an additional 10,000 restaurants have closed nationwide," he said.

"For every month that passes without a solution from Congress, thousands more restaurants will close their doors for good."

Meanwhile, 58 per cent of chain and independent restaurants expect continued furloughs and layoffs for at least the next three months, according to the National Restaurant Association.

Despite an unabated resurgence of new coronavirus cases across the country, Democratic and Republican lawmakers have been deadlocked for months over the size and scope of the next relief package.

In a letter to Congress on Monday, the US Chamber of Commerce warned that the failure to enact a meaningful pandemic package "risks a double-dip recession that will permanently shutter small businesses across the nation and leave millions of Americans with no means to support themselves and their families".
