The Fernsehturm Berlin is an iconic television tower in Berlin from the German Democratic Republic (GDR) days. There is a restaurant within the tower at 207.53 metres that offers a fantastic view of Berlin. I found the tower to be a nice place to visit and to get a nice dinner at the restaurant which rotates every 30 minutes. If you stay at a good hotel, the hotel concierge should be able to get you a reservation for dinner at the restaurant along with a preferred entry where you don’t have to wait in a line. The preferred entry ticket costs about 22 Euros per person. I think its worth it as you can spend some time at the observatory and the restaurant and avoid the lines. Without a reservation, there is little chance of getting to eat at the restaurant although you could get a few drinks at the bar at the observatory. But the food at the restaurant is really good and worth checking out.
The Alexaderplatz area which is right next to the tower is a nice place to sit around watching people and you should also check out the Neptune fountain that’s close by while you visit the Fernsehturm.
