Berlin needs its own Top 10 list, this city has got it going on.

1. Go and see the East Side gallery, some of the last remaining intact parts of the wall covered in graffiti; near the Warschauer U-Bahn stop

2. Drink a beer at a Biergarten. With communal tables set up you are sure to meet some new friends.
3. See the zoo, located in the heart of center city. The monkey cages are awesome.
4. Experience Museum Island- just like it sounds, an island chalk full of museums (best one is DDR Museum, showing daily life in East Berlin)
5. Eat a donner kebab. Berlin is full of relocated Middle Easterners and the food is to die for.
6. Go to the Check Point Charlie Museum. See how East Berliners tried to escape during the Wall years. My favorite is the shopping bag.

7. Trace the original pathway of the wall. Small bricks have been painstakingly placed into the asphalt to trace the original wall dividing the 2 Berlins.
8. Take the S-Bahn and U-Bahn everywhere you go. An amazing feat of Germaness and one of the best transit systems I have ever used.

9. Make a hotel reservation in the East Berlin, some areas are still eerily reminiscent of DDR times and the lack of western influence is apparent
10. Hit a music/club/art venue. Berliners are some of the coolest folk in the world and know how to have a good time.
11. Visit any of the flea markets around the city, there are plenty of old beautiful things to find. (submitted by Hotels Barcelona)
