lunchtime in Adelaide

I still find it a depressing experience walking Adelaide's CBD post-Covid. Many of the lunch time cafe's and coffee shops continue to remain closed.  Will they ever open again? Will the pandemic shape Adelaide's future? What  might urban life look like on the other side of the Covid-19 pandemic?  How long before the CBD starts to be full of people? 

Judging from the lack of people in the city it appears that  many of the office  workers are still working from home. The density of the people in the city is certainly much less than in pre-Covid times and about half those walking the streets are wearing masks.  It was such a marked difference to Melbourne where hardly anyone wore face masks on the street.
