The cheapest way to eat is to buy ingredients and cook it yourself.
Restaurants buy ingredients, and cook, but also have to add costs like rent and labor. Thus as money supply constricts businesses like restaurants see a slow down in customers.
The current economic policies in the US are explicitly designed to raise the prices of goods and services like health care. This will, as a first order effect, reduce the disposable cash available.
Restaurants will suffer first, they are a luxury easily and quickly discarded. But they are the canary. Expect to see all kinds of businesses, especially small businesses suffer, as these policies play out.
And just remember, you voted for this, and many people explicitly support these policies and their effects. These are not bugs, they are explicit design goals.
