I have to say that on the day we were booked to go, I stupidly read a whole bunch of the negative reviews here... and almost cancelled our booking.. I'm so glad I didn't because we had a lovely time and really have to say that Nahm is a wonderful restaurant.
I have no idea what it was like with David Thompson, but with the current chef, it was a fun night with terrific and delicious food.
It's by no means perfect, but all these reviews carrying on about how tasteless it is, with such poor service and ambiance are just rubbish... so ignore them all. Or take them with a grain of salt.
The service was excellent. I suppose the only criticism I would have is that the meals came out way too quickly. There wasn't much (if any) of a break between what we had.
But in terms of flavour, yes it was great. Service was very good also. Some reviewers mentioned price, but honestly, that's just what a good restaurant costs, so I'm not sure why they were surprised or annoyed for having to pay for water. You pay for water at Subway.. so why should a top restaurant be any different! We had their version of a tasting menu, but it would have been much cheaper if you just chose normally from the menu. I think it cost something like AU$450 for two, with a bottle of wine which cost maybe one third of that.
I don't know if I'd necessarily give it a Michelin Star, but that certainly shouldn't detract from what it is, and what is presented. My wife and I had a great time, and enjoyed it much more than Gaggan, which we'd been to two nights earlier.
