Well, maybe second best, after Tetsuya. But then again, I used to think Est was about on a par with Quay and Aria, but in the last couple of years they have taken a step up.
The service is just astounding, I doubt it is better anywhere in the world.
Food is exceptional. Right up there and close to the best of the best in the world.
Wine list is rightly considered one of the best in Sydney. Though a bit pricey, even by 3 hat restaurant standards.
The only thing that every so slightly lets it down is the ambience and the décor, but that is being really, really nit-picky.
