Alexanderplatz is a living area full with tourists and people enjoying the space around them. A lot of high end brands as well as normal quality shops are available for all kind of people. You can eat at any restaurant you like while you plan to go to the TV tower which is standing right here at Alexanderplatz. A must visit when coming to Berlin.
A huge area filled with shops, restaurants, cafes and bars, many beggars and people selling stuff will come to you so be careful if it's your first time in Berlin. But overall the place is friendly and crowded with lots of movements. You can also visit the TV tower.
