I'm going to Berlin in the beginning of April (Easter holiday)?

Any tips about what to do, where to go (culture, eating out etc..)?

Berlin is a great place and there is so much to do and see. Get some little book about Berlin and look over it, what are you interested and make some marks on it.
The city is so big and you can shop, museums, there is so much.
Have fun... I was there 4 x and can not get enough.

Shop at the KaDeWe, visit the Kaiser Wilhelms Gedachtniskirche, the Checkpoint Charlie Museum (if it's still there-- it was in 1995), the museum "Questions in German History" (Frage in Deutsche Geschichte) in the lower level of the Reichstag, climb to the top of the Siegesaule (385 steps!), I could go on and on.

Please go there
You do any thing All your choice

Go to the official website of Berlin at http://www.berlin.de - and also the tourism website of Berlin http://www.berlin-tourist-information.de... - both websites are also available in English language.
I am myself living in Northern Germany...Berlin is a great city and you surely might find anything you want. If you go to a search engine (Google, Yahoo or Exalead.com), you can also search for museums in Berlin, restaurants, etc....Enjoy your great stay!
Remember that weather in Germany changes very quickly, especially in April - don't forget to bring an umbrella with you - sometimes, weather also can be quite warm & sunny in April, but that's really not predictable.

Again, have a nice time in Berlin! :-)

Greetings from Germany

Get a decent guide book before you go.

DEFINATELY go to the top of the t.v. tower. I think it costs 9 Euros, but it is worth it. Go on a clear day and you will get an incredible view of the city.

There is this places with the best Chiken in the world and only 10 Euro it is called Markthalle and drink FassBrusse

nice trip

Spend at least one evening at one of the countless bars / cafes / restaurants in the Prenzlauer Berg district. Most have wooden tables and chairs with candles on the table, excellent food and service at prices you can only dream of in other major European cities. If you like Tex-Mex to to Joy in the Sredzkistrasse - this is my favourite. Otherwise go to Kollwitzplatz or Rykestrasse. The choice is huge.

The area is really buzzing, full of young people!

You can visit Stasi Central of the DDR! It麓s very interresting and i think they have English guidance !

YOU MUST SEE THE WORLD CLOCK.... its pretty cool

Consult your guide or the www.berlin.de
In any case, do not go to Charlie's point, it is just for tourists and Alexanderplatz (very grim and disappointing) - instead walk around the area Potsdamer Platz (great architecture), Branderburger Tor, Unter den Linden, Friedrichstrasse and if you are the type visit one the 100s of museums (I like Pergamon, or Neue StaatGallerie or Bauhaus Archiv). Eating and drinking is cheap and Germans are very friendly and polite. And shopping can be exciting in Hackischer Markt (if this is spellt correctly).
