We did the reverse route this past October. We atttended the 12:45pm chanting at Sant'Antimo and then drove to Il Leccio for lunch. Even in early October, the patio was completely full at 1:30 when we arrived, so we ate inside. We had made reservations, which was fortunate. You can drive right up the hill so that you are fairly close to the restaurant without any danger of entering a ZLT. The road was very pretty and it was a lovely drive. It was under 1/2 hour to get there, as I remember. I honestly cannot remember the wineries along the way - I think I was too hungry and focused on getting to Il Leccio!!
