Outdoor seating you should be fine so long as employees take proper precautions.
I think we will venture out soon to do just this. Friend and wife whent to Chimes this week- sat outside and said everyone was in proper attire and tables were 10 ft apart - he is a CRNA - so i trust his judgement.
I guess if its overly-crowded and busy, that is up to you. But venturing out for a meal where precautions are adhered to, should be just fine.
