Maybe you could go speak with them instead of complaining here.

City Hall – DR assigned this issue to License Commission

I think opening the door is important in the current health crisis, but they should not begin until 7:00 a.m.

Thank you for the information I will contact the business and let them know of the residents concerns. If you have any further questions or concerns, please contact me directly at aboyer@cambridgema.gov. Thank you again, Andrea

This is the appropriate venue to share these concerns, versus potential conflict or misunderstanding. It also helps the City identify patterns and manage things comprehensively. There’s also the fact that some people, with the COVID public health emergency, might consider it unsafe to approach an establishment where there’s lots of heavy breathing taking place.
