Not much of an update but here it is...
Spoke with a lovely and helpful CM, trying to book dinner Feb 26th. She said times didn't appear to be loaded yet. She offered to check if anyone was booked for dinner that evening (she checked 6-7pm) and found NO reservations. She suggested I keep trying, of course.
Don't know about this one, but she said Le Cellier may not have signed their agreement re: the dining plan for the upcoming year, which is due by December, and this might have something to do with it...
