Recently a new hotspot opened in Amsterdam North: A’dam tower. From the 2oth floor you will have a spectacular 360 degree view from the Lookout. Behind Central Station you can take the (free) ferry to Amsterdam North. After the astonishing experience you can get yourself together at Madam for drinks. We definitely advice you to go around sunset and stay till whatever time you think is apropriate 🙂
You can make a reservation in advance.
