Anecdotal, but in my area (Eastern Europe) restaurants are still half empty, even after accounting for the reduced number of tables to allow for social distancing and after accounting for the indoor areas being closed. So at best, they are probably doing a quarter (probably less for most) of the business they were doing before. This is in the largest city in my country.

Gyms are also almost empty. Tourism is surprisingly less affected, and I would imagine that restaurants in tourist places are much more full. But outside of those, it is definitely NOT business as usual.
