Not only for what all other travelers already commented: the impressive decoration, each of the floors is different, the cocktails in the bar, the menu in the restaurant, the splendid terrace... The atmosphere is simply great. You feel as if you were in a world where all fantasy is possible, where the customer is the most important.
I went there only one night, but thanks to a special offer on their website, which I recommend checking out. The price included two cocktails at the bar and two other ones on the terrace. Parking was also included, which was supposedly free of charge but we had to pay half of it (check it before going).
