Nope not really. Been to it a few times and I dont need to go back. To many people. I would rather go the local ones like in Nurnberg where only a few hundred thousand people attend instead of 6 million. Same thing though, only less people. Therefore I like the local ones better.
Now having said that, the Oktoberfest is a must to attend atleast once in your life just to experience and say, I did the Oktoberfest.
TPBM really would like to experience the Oktoberfest.
