Isn't this just a problem due to money-losing competitors selling at low prices? Getting restaurant food delivered is a waste of money compared to getting bulk food delivered from supermarkets, so those who order it are probably not very price sensitive, and thus simply raising prices until the company is profitable should work without losing so much customers that economies of scale are lost, assuming there are no money-losing competitors.
