Tasting Menus - Canoe, C5, or George
I've had all 3 (but not too often).
Canoe's (within the past year) was expensive but excellent. If someone else is paying - that's where I'd go!
George used to be impressive - but my last time (a little over a year ago) showed signs of stress - but that was on a busy night. But also very expensive - and I think Canoe was better.
C5 was a disaster (for me). But also a year ago (a few months after they opened). The food was uncordinated - the progression made no sense and the service was worse than the food.
Haven't been back - so I'd say the higher risk was here.
But 2 years ago I would have picked George - so hope that shows you where Canoe sits.
A further hint - avoid the cheese plate at Canoe (it was an optional extra) - ridiculously expensive for what you get.
I had a tasting menu at c5 a couple of years ago, courtesy of some very generous family members. I don't remember much, but I do remember that the food and service were both impeccable. Perfect, really. I don't remember many restaurants leaving such a high overall impression two years after the fact.
