Unless a restaurant has deep pockets, fighting to stay alive through conducting any business possible is the best recourse. This may not make up for all operating expenses including paying the rent and feeding your family, but it’s better than nothing. Beyond the ability to change a restaurant's business model to fit the limitations of closed dining rooms, supplemental financing may be required to keep the business afloat. There are financial tools that are used to raise capital and make up budgetary shortfalls. They are: 1) Debt Financing 2) Equity Financing. There are other options like grants, which are similar to receiving a scholarship, however these can be competitive due to their “free money” nature and are never guaranteed until the check is deposited.
