No restaurants were physically destroyed by the pandemic. All the buildings, stoves, tables, signage, etc are still around.
The skills of the workers will likely fade only slightly during this pandemic time.
There's likely not much reason to think that in 2022 the dining habits of consumers will be drastically different than in 2019. There wasn't a restaurant bubble prior to 2020 necessitating a huge correction.
Also it's worth noting that government edicts likely aren't the primary cause of business closures at this point.
People (selfishly) don't want to catch the virus and also want to listen to public health advice.
Evidence:
-There were never any real government edicts banning air travel in the continental US (some few places had non-enforced quarantine advisories). Yet air travel has fallen substantially.
-Most large businesses have not returned to in-office work, regardless of no government edicts.
-Las Vegas is Open! You can fly there, stay in a hotel, gamble, eat, etc... but yet Vegas has tons of closures. People just don't want to go there right now for business or pleasure.
