One thing restaurants could do is seat random strangers together. I had a great meal at Absalon, a cultural centre in Copenhagen, which does just that. Recommended: https://absaloncph.dk/en/food/
I eat alone when I'm traveling and want to catch up on HN after a hard day at a customer site or if I had a hard day in general and want some me time (as cited by the article).
Last thing I want to do is have the usual conversation with a stranger that I will never see again.
Not every restaurant experience needs to be a social one.
Dear god no. What an absolutely disgusting idea!
