We had lunch in this restaurant after a friends recommendation. We enjoyed it very much.
The food was very good. From the steaks, to the sauce and side dishes. The desert was also very nice.
As mentioned by others the view is also nice, even though the city view is partially covered by another house. Going up the road you find a couple more restaurants with a better view.
The price is a bit high in my opinion. A lunch for 4 people with main course, desert and not so many drinks costed 135 euros. I ate better in the Czech Republic for one third of the price (but not in Prague, that makes a difference).
They only allow smoking after 22h, which is a bliss for people like me who hate places where smoking is allowed.
If you are looking for a nice meal and you are not in a budget, I recommend the restaurant.
