I've been here twice, both with large groups. The staff is great at servicing a large group well and making everyone feel like they're in a luxury restaurant. It probably helps that they are in a luxury restaurant, but still great service.
Food was very good. What you would expect from a place with a strong reputation like this. If you ask a concierge where to go, good chance they will point you here.
I'd definitely go again, and also be interested in trying it with a small group.
