As I found it was a not a cheap restaurant; but it is also true that you are only going to pay for the meal, the view is for free. The whole view is unbeatable but it is better for everyone to go when the day was clear.
Key point is that the restaurant is that the floor is revolving and that it covers whole scenic view in just 90 minutes, so it is one of the major attraction factors. Apart from that, the food was delicious.
