A $28.6 billion grant fund for restaurants, bars, caterers and other food businesses will open Monday, the government said on Tuesday, offering an extra lifeline to some of America’s hardest hit small businesses.

The Restaurant Revitalization Fund, which was created last month by the $1.9 trillion American Rescue Plan, will offer grants of up to $10 million to replace lost sales. The amount each businesses can receive is generally the difference between its 2019 and 2020 gross receipts, minus certain other federal assistance such as Paycheck Protection Program loans.

The money is expected to go quickly. Eligible businesses have lost hundreds of billions of dollars, according to congressional estimates, but lawmakers provided funding to cover only a sliver of that total.

“Restaurants are the core of our neighborhoods and propel economic activity on Main Streets across the nation,” said Isabella Casillas Guzman, the head of the Small Business Administration, which will disburse the grants. “They are among the businesses that have been hardest hit and need support to survive this pandemic. We want restaurants to know that help is here.”
