Years ago, I did a big group thing two different trips.
CRT were wonderful to us and it ran smoothly. Chefs de France, I think pushed tables together, and it seemed a burden. But it depends who the wait staff is. We had some very dry, no-nonsense waiters that trip to Chefs. Sci-Fi was very accommodating too.
And even though we are no longer dating, Le Cellier was great for a big group at dinner service. LOL!
I also did for the first and only time, Victoria and Albert's with a group of 7 and the service is impeccable. They were friendly, didn't rush us, and were meticulous.
