That's what's happening now. The price and difficulty of obtaining materials and ingredients is up and rising. Shipping is up and rising. Rent is up and rising. Getting labor and labor costs are up and rising, which isn't necessarily a bad thing, but is happening nonetheless. And restaurants are still on their back foot after 2+ years of business disruption due to COVID. The prices on the menu need to go up to account for this and take advantage of all of the customers, but you can only raise prices so much before demand drops. And that's how restaurants are getting squeezed out of business.
