The firm I work for did catered lunches daily before Covid, and seems to be rebooting the process as people returned to office. (I'm remote, so I only experienced it during occasional returns to the mothership)

I suspect part of the percieved value is that by making lunch a communal event, rather than everyone grabbing 30 minutes sometime between 10:45 and 14:30, means it's also a time for face time outside of group lines. If you need to talk to someone on another team, you usually have a chance to make contact at lunch.
