At the 1982 World's Fair, I worked at the Strohhaus. It was a blatant attempt to inject Hofbräu- or Ofest-ness into the affair. They even had an oompah band and overcrowded seating and everything. If the USofA can export Micky D's and the like, we can most certainly import the similar vein of other cultures. Why not, its fun! You don't see people complaining about the Chinese, Indian or
Italian restaurants on every corner of the world do you?
To be honest, it tickles me pink that there are more German (and French) themed restaurants in the States than oh say British ones.

@hilaryf, during the UT-Bama game weekend (in '82) the oompah band played Rocky Top and the crowd went wild! The Bama section and the UT section were singing back and forth at one another and it was, as I have found out since, very much like what happens at the Ofest between Italians and Germs or anything to do with soccer. It is stupid fun, but beer fueled fun none the less and everybody knew it and no one took it seriously enough to start fighting.
