Very bad experience. The service is extreamly slow. You need to wait about 15 min to get a menu, about 20 min for waiter to take your order. I ordered Aperol. I have to wait more that 30 min to get it. The waiters were roud, and when i came to the manager he said he can do nothing. Not even appologies. As this place has a very good view on the city from the top of the hill, the restorant just make use of it. "You are just one from 2000 per day", that what manager told me in my face.
