Do they plan to go back to being open 24/7 again? Tbh these excuses for changing hours based on the pandemic are getting old because there are no state or local restrictions on business hours anymore...........

I'm not sure. You might want to contact restaurants in your area concerning reduced hours or if they plan on returning to normal pre pandemic hours. Various locations likely are different.

I don't think they are open 24/7 anymore. I think it has to do with the labor shortage.

You should probably contact them directly to ask about a change in hours. But to your point, even if they aren't mandated by COVID restrictions to reduce their hours, a lack of customers staying in due to COVID may explain not being open 24/7.
