Anniversary dinner in town of Sonoma or nearby
I would choose La Haye over Hot Box in a flash. But the only time I went to Hot Box was soon after they opened, and the food was fine, but the service was snooty. I haven't been back, but others I know/respect like it, so I think it was a fluke.
But La Haye is always a pleasure. It is small, so reservations are necessary, and they have a tendency to avoid seating 2 tops later in the evening, so you might have to eat earlier than you like.
