Just thought I would add that back in August we had ADR's at Le Cellier for 5:20. The couple in front of us at check-in walked up and were able to get seated that night for dinner with out having an ADR. Now, I do have to add that the next day we figured we'd try to see if we could do a walk-up for lunch with no ADR, and the place was packed, and we were definitely NOT the only walk-ups turned away. So, I guess you can sometimes get lucky, but not usually.....
