I'm surprised you were able to book this time since all indications are the restaurant closes between 3 and 4 meaning they don't they don't take reservations during that hour so that lunch diners are finished and out of the restaurant before the dinner seating begins. I wonder if they're extending lunch and pushing back dinner hours once it becomes a Signature restaurant on March 1.
I wanted to go for lunch, but couldn't get in..........so I made a dinner reservation. I decided to keep my Bistro de Paris reservation and when I cancelled, the guy on the phone seemed stunned that I would cancel a very hard to get reservation at Le Cellier, lol.
