For Le Cellier - KEEP CHECKING!!
I literally just scored a 12pm ADR for our trip in December thanks to religiously checking the system online for weeks. It seems like they just randomly pop up with availability. When I saw it come up, I screamed with excitement, while DH just looked at me like I was crazy.
So just keep checking!
