I called about 6 weeks before our May trip and was unable to get an ADR for 5 people for either lunch OR dinner. I also tried several times up until our trip with no luck. I was able to score CM, 1900, and CRT (which we ended up choosing not to do), but no luck with le cellier. Of course, having 5 in my party made getting tables at a late date more difficult than for a group of 4 or smaller. If you want to eat here, definitely make an ADR. We're looking forward to our dinner at the end of the month!
