Munich is a multicultural city, people from all over the world live you and also many tourist visit the town during all the year (not only for the Oktoberfest).
That’s give to Munich an interational status, if you come from the other side of the world, for tourism or living here, be sure, you can find what you need coming form your own country.
There are markets specialized in asian food, or african or from every part of Europe as weel as restaurants or shops selling different kind of clothes.
I think people from other countries are living here in a good level of tollerance.
I can say that Munich is a modern city but thigtly traditional at the same time, in the street and not in special days for special events, it’s easy to meet people of any age wearing their traditional dress … AMAZING !!!
