The family dining / lower causal dining market segment (relatively cheap sit-down restaurant, with a waiter) is being squeezed pretty aggressively. The fast-casual segment (order at the counter, but not fast food) was already growing before the pandemic, and those were much better suited to pivoting to take-out and delivery when COVID hit.

As a whole, Americans are demonstrating that they care more about the food quality than the service at a restaurant, by eating at restaurants that, holding price approximately equal, sacrifice service in exchange for better food, rather than eating at family-dining establishments that do the opposite.
