microcovid.org helps you understand risks of getting Covid with various activities based on current scientific evidence. Takeaways: eating indoors once a week is probably too risky for me (~3% chance of getting Covid in a year), but outdoor dining is fine (~0.1% in a year). Most outdoor gatherings will be much safer than indoor ones. Plane rides are relatively safe as well.
Obviously these estimates should be taken with a grain of salt is there is enormous uncertainty here.
