The TV Tower is a must, the lift is that quick its almost like being on a roller coaster when it gets to the top.
A spectacular view of the city.
Brandenberg gate is also a must. Not much to see, but a place mark in history.

The new incarnation of an old techno institution, Tresor Club is set in an industrial former power station spanning 22,000 square metres on Köpenicker Straße in Berlin's Mitte neighbourhood. It consists of three floors: Globus, the +4 Bar which has views of the old power station ruins and the famed basement which can be reached through a 30-meter long tunnel. During the summer, there's also a smoker's garden. The club is open every Monday, Wednesday, Friday, and Saturday.
It used to reside in an old Bank Vault, one hell of a club still with the vault bars still in situ.
