I'm also making that prediction. Restaurants are especially susceptible to enshittification. I remember when I worked at Ruby Tuesday in the 90's, it was upscale enough that all servers wore a shirt and tie. They were big on polished brass and wood interior, coupled with above-average food made mostly fresh. These days, it's a glorified Burger King with a salad bar.

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.
