I'm not sure that restaurants will have to permanently raise prices, but it's logical to assume that there is a sweet spot where a restaurant can draw 25% of it's capacity and stay afloat.. Prices will be set by demand. What will impact that demand is a) capacity, b) the amount of discretionary disposable income people have, and c) the willingness of the customer base to go to a restaurant. Here's the problem, though. Some large chains have the financial wherewithal to keep prices artificially low while small restaurants cannot. So we might see the old airline model, where larger players can merge and put the competition out of business. So unless we get these restaurants some help, the landscape will change. I suspect our favorite locally owned restaurant will probably go out of business. But the Olive Garden and Red Lobster and Chili's will not. But at some point, capacity and demand will increase, prices will come down, and entrepreneurs will begin to open restaurants again. It's a long haul to getting back where we were, but it will happen.
