Klal yisroel loves Hashem Batei medrash and shuls are packed to the brim with people on top of ech other. This is obviously a beautiful thing.
Unfortunately when there is a disease spreading this is a bad thing.
On the other hand Klal yisorel has no inteest in restaraunts, these places are always desolate , פיסט און ליידיג so there is no reason to close them .
Though, at any rate as far as I’m aware restaurants (at least in my neck of the woods) are open for takeout only. they ARE closed for dining, Is this not the case where you live?
