As of right this moment ( March 16 2020 8:24 PM PST) yes they are. Effective at midnight tonight all residents of the SF bay will be ordered to shelter in place, meaning all non essential travel is frowned upon. That being the case, they probably won't reopen until April 7th 2020 when the restrictions on travel are lifted.
Most restaurants are serving food as take-out or delivery only during this home shelter period.
