Se·sto on Arno is a rooftop bar on the sixth floor of a five-star hotel in central Florence, looking out over the Duomo and the Arno River. It serves cocktails, snacks, and main dishes, and guests can have an aperitivo while facing the river. The rooftop has 180-degree glass windows, so the view differs between day and night, and reservations are required. There have been cases where waiting more than 10 minutes for the drinks menu, and prices are high.
