2) Tree Restaurant, Auckland. It's suspended 10 metres up a huge redwood tree and it was designed on a child fantasy of a tree house. I am fully aware this is not a tourist attraction or a magnificent landmark but I couldn't resist and it actually is on my list. The only downside is that it is not longer open to the public but it can be reserved as a private party for 30 people. I can see myself renewing vows there.
What an unique experience of fine dining!
3) Champagne pool in Rotorua was formed nearly 900 years ago by a hydro thermal eruption and it's temperature reaches 74°C. It was named Champagne pool because of it's resemblance of a bubbly glass of famous sparkling wine. The unusual coloring is mostly from arsenic and sulfide deposits. And I found it visually so beautiful it makes me want to go right now!
