I just made an ADR for Le Cellier today, for Thanksgiving. The CM I spoke with said they release a small number of seats daily, for that week. I guess it gives everyone a fair shot. I would keep calling.....
I've heard Le Cellier is about has hard to get into as CRT and you need to use the same booking strategy. Do the exact at 7:00am call and speak as quickly as possible with the pertinent info. And try an off time. I got a 12:55 ADR.
