Don't go if you have kids, even though they have high chairs. The owner should be in an industry where he doesn't need to smile or be warm to his guests.
I went back a second time just to confirm that my experience wasn't simply a bad day. It wasn't. He is simply miserable. Who needs to spend that kind of money and be made to feel one should be grateful. I'll go elsewhere, service is usually so good in Oz and generally people are warm and friendly. I can only assume he has had an awful week or business isn't going to well. There were only a few people there and mixed reviews on line.
Plenty of other great places to go.
