My wife and I had a fantastic anniversary meal at Georges Trois last night. If you have great memories of meals at Le Francais or Le Perroquet, you can go here and re-experience traditional French cooking at the highest level.
The setup: The "restaurant" is a small room inside Michael's. It has 6 or 7 tables. The door to the main restaurant is kept closed, so you are in a very quiet secluded area.
The ambiance: This is old school. It's quiet but not stuffy. Men are required to wear jackets. Chef Lachowicz comes out and greats every table, and then personally serves every course except for one of the desserts. What I particularly like is that they do not turn tables. They have a few seatings, but that is just to spread out when people come. Our 12 course meal started at 6:00 and finished at 9:30. Lot's of time between courses to relax and talk. It is a full evening's entertainment.
The food: no molecular gastronomy (which I love), and no unusual flavor combinations where you go "who would of thought of that!" But excellent ingredients, attention to detail, and top of the line old school French cooking. Last night's menu featured Perigord truffles in most of the course. We liked the portion sizes because at the end we were full, but not overstuffed. Lot's of small portions of very intensely flavored food. I had to get a second piece of bread to that I could sop up every drop of every sauce. Mostly meat, seafood and starch; very little vegetable.
So sum up: a quiet room, a leisurely pace, and food that was just damn delicious. For a special occasion, I'd go back in a heartbeat.
