Sociale? Any recent reviews?
I've had quite a few excellent meals at Sociale, but our most recent meal organized for 8 was really too much for the kitchen to handle. They didn't indicate it could be a problem, but the food really suffered. I recommend 3 people or less, but 4 is certainly doable. They have a wonderful wine program with an ever changing list of interesting affordable Italian wine.
I eat at Sociale several times a month partly because it's in my neighborhood, but mostly because the food is so reliable and good, the service is excellent, and the prices are very reasonable for the quality level. If it's not pouring rain the courtyard is really nice, powerful heaters beat many San Francisco cold evenings. The restaurant is as good as it's ever been, and many dishes have been on the menu for years, so the old posts can be relied on.
