Working and traveling in the EU

[lordron]

I have a question of a more general kind, but it is still specific enough I think to be posted here. I am am British citizen and I intend to do a trip through Europe. But I do not simply want to travel, since I have to earn some money "on the way" so to speak. I think it is possible to work in the EU without much bureaucracy, but I wonder how much preparation it still requires to get a job in a foreign country? I am talking of jobs in the service sector (I am a trained cook and bar keeper).
The countries I intend to visit are Germany, Switzerland (interesting as it is not EU), Italy, Portugal and maybe the Netherlands.
Thanks for your replies!

Obviously you need to prepare CV and register with job center there.
