I've been there only once but I still like this place very much. Prices are a bit on the higher side, though.
It's very clean but not sterile, the personnel is friendly.
Pizze are very thin and crispy, my "Quattro Formaggi" was excellent!
While writing this I made my mind up that I have to go there again soon...

I was there with my wife and oldest son 4 times and very time we saw friendly people behind the bar, the food was very good and on Thursday evening the had a quiz.
The quiz was good fun and for me as an Austrian, who has never experienced anything like this before, absolutely cool!

I was there some years ago - rather expensive and nothing really special. For my taste it's pretty much hyped...

I like this place very much! Their menu card is pretty hard to choose from as there are frequent seasonal specialities (e.g., Asparagus weeks, Mushroom weeks, Pumpkin weeks) beside a very complete choice of meals.
I second p.bird's review regarding the fact about the clothes smelling for quite some time after having left there.
The separation between smokers and non-smokers is relatively well done, but it very much depends on where you sit.
All in all I like it very much!

I loved that place whenever I was there!
The food was very good though not the greatest, the Margeritas were perfect (for me!).
But the greatest about this place is the scenic view you have from their expansive platforms.
