Much if not most of the “outdoor” dining is with partial walls and often roofs. The key difference from indoor is open ventilation. However, they use heat lamps and heaters which tend to blow the air around the area and often downward. Doh!

That's certainly the case at present and apparently at the French Laundry. However, until mid November, Castro Street dining was completely open air.

did they have heaters at night?
